FAQs

STTOKE cups and jugs are made from 304 food-grade stainless steel, BPA-free, and lined with German-engineered Greblon® Ceramic for a cleaner-tasting drink. The exterior isn't built for rough handling (see Care & Cleaning below for tips on keeping it scratch-free).

Coffee, matcha, tea, hot chocolate, juice, whatever you're drinking, the ceramic lining keeps it tasting like itself. With double-wall insulation, your drink stays at the right temperature for up to 6 hours.

Safety note: Liquids above 75°C can build pressure within the cup. Keep your Leakproof/Splashproof Lid open to release it, and always open it facing away from you.

Designed in Melbourne, Australia. The Greblon® Ceramic application is completed in China.

A heat-cured, dry finish that’s slip- and scratch-resistant and dishwasher-safe. Powder coating products are available in the Earth Series (8oz, 12oz, 16oz, and 20oz), Swirl Cups and the Sharing Jug. Our powder-coated products are more durable and convenient to leave in your bags.

Best to handwash (unless stated otherwise). Rinse before first use, then wash with warm, soapy water and a soft sponge before each use, and air- or towel-dry completely. Only the powder-coated finishes (Earth Series and Sharing Jug), lids, and tea infusers are dishwasher-safe (top rack). Not sure about your finish? Email us at hello@sttoke.com.

Hand-wash gently in warm, soapy water using a soft-bristled brush on the drinking edge. For a baking soda soak:

• Mix 1-2 tablespoons of baking soda with warm water and soak for 30 minutes.
• Wash your lid with mild detergent and rinse.

Don’t detach the black flip /tab because it is designed to stay in place. Store your cup with the lid off so everything can dry completely.

Yes, with a wooden or silicone spoon. Skip metal, glass, ceramic or sharp utensils, which can scratch the interior coating.

No, the stainless steel body isn’t microwave-safe, and fridge or freezer temperatures can damage the vacuum seal.

Our Earth Series anodising is the most durable to friction. The others are porous by nature. Avoid loose bags or heavy friction. Check with our customer support team at hello@sttoke.com for more clarification.

• Kerrie Sleeves & Sttrap (vegan leather): wipe with a damp cloth, blot spills immediately. Do not machine wash.
• Kerrie Polly Sttrap (woven): wash gently with mild detergent and warm water, then air dry. Do not machine wash.

Hand wash the lid as usual. Clean the extension base with a soft sponge and dish soap, and use a straw cleaning brush for the caps and straws. You can also use the baking soda soak method:

STTOKE cups and jugs are lined with Greblon® Ceramic, which is odourless and stain-resistant. However, frequent coffee or tea use could cause mild discolouration or lingering smell over time. To clean naturally:

Method 1: Baking soda soak:

• Mix 1-2 tablespoons of baking soda with warm water and soak for 30 minutes to neutralise the acids.
• Wash your lid with mild detergent and rinse.
• Rinse and air-dry your cup or jug.

Method 2: Vinegar solution:

• Mix equal parts of white vinegar and water
• Let it sit for 20 minutes to break down alkaline stains, such as tea stains.
• Rinse and air-dry your cup or jug.

If odour persists, fill the cup with boiling water and soak for 2 hours before washing again.

Still an issue? Get in touch with us at hello@sttoke.com

IMPORTANT: Avoid using hard sponges, metal spoons or sharp utensils, as they can scratch the coating. Damage caused by improper cleaning is not covered under warranty.

Email us at hello@sttoke.com, and we will take a look.

The Omni Cup* was our original 8oz cup, coated with the same Greblon® Ceramic and built with a Splashproof lid. The Omni Cup has a flat inner bottom.

The new Commuter Cup range (8oz, 12oz and 16oz) is designed with the same Greblon® Ceramic coating and with the following upgrades:

• Leakproof Lids (versions 1.0 or 2.0), which means the cups have screw-thread.
• Parabolic Bottom (inner cup)

*NOTE: The Omni Cup has been discontinued since 2023.

No, if you have an original Omni cup and older Splashproof 12oz cups, the new leakproof lids won’t fit. Only the new Commuter Cup range is compatible.

Splashproof lids are compatible only with Omni and Splashproof cups. Leakproof Lids 1.0 and 2.0 are compatible with Commuter Cups in 8oz, 12oz, and 16oz sizes. Leakproof Lid 2.0 for 20oz is only compatible with the 20oz Leakproof Straw Cup. Check the product descriptions for more details.

No, there are specific Kerrie Sleeves:

• Kerrie 8oz Sleeve is compatible with Commuter Cup in 8oz.

The 20oz Leakproof Straw Cup itself is only suitable for room-temperature and cold beverages.

Yes, the straw lid features a spill-safe valve and a sealed straw tip, making the cup leakproof when kept upright.

There are specific accessories for the 20oz Leakproof Straw Cup:

• Leakproof Lid 2.0 for 20oz
• Kerrie Bags

The following accessories are not compatible with the 20oz Leakproof Straw Cup:

• Splashproof Lid
• Leakproof Lid 1.0 and 2.0
• Kerrie Sleeves and Kerrie 8oz Sleeve
• Tea Infuser
• Hydrate+ Extensions
• Commuter Pop-In Straw Set

Yes, remove the internal valve for easier flow (it will still be leakproof with the straw-tip cover in place), or keep the valve for more control.

The Sharing Jug is a 20oz jug for both hot and cold drinks, designed for sharing and hosting. The Sharing Jug shares STTOKE’s signature parabolic bottom and is coated with Greblon® Ceramic.

• Hot: up to 6 hours
• Cold: up to 8 hours

On average, the Sharing Jug can serve 2-3 of our 7oz Swirl cups. This depends on how generously you pour.

Yes, the Sharing Jug is dishwasher-safe. The jug comes with a silicone lid to retain the beverage temperature.

Both Swirl cups come with our signature parabolic bottom and Greblon® Ceramic coating.

7oz Swirl Cup features:

• Hot: 30 mins to 1 hour | Cold: up to 2 hours.
• Complements the Sharing Jug best as a set.

12oz Swirl Cup features:

The Kerrie Sleeves, Kerrie 8oz Sleeves, Kerrie Sttrap Extensions are made of vegan leather. Kerrie Polly Woven Sttrap is made of polyester vegan leather. Kerrie Bags are made from Axoflux 2300D (100% recycled 2300-denier polyester).

Yes, all of our Sttraps (leather and woven) come with a double hook-and-ring design that lets you switch up how you want to carry your cups in seconds.

• Kerrie Sleeve & Sttrap with Extensions (vegan leather): wipe gently with a damp cloth. For stubborn dirt, use a mild soap solution and a soft cloth. Avoid soaking. Dry with a clean towel, then let air-dry completely. Avoid exposure to excessive heat and humidity.
• Kerrie Polly Sttrap (woven): to clean dirt, use a soft and damp cloth or sponge. Wash with gentle detergent in warm water and scrub with a soft-bristled brush. Air-dry to maintain the material integrity. Keep away from direct sunlight to avoid weakening and discolouration.
• Kerrie Bag: hand-wash only using cold or lukewarm water (below 30°C / 86°F). Use mild, non-abrasive detergent. Do not bleach, tumble dry, iron, or dry clean. Air dry in a well-ventilated, shaded area. Avoid direct sunlight to preserve material integrity and colour.

• Splashproof lid: Omni 8oz Cup, Splashproof Cups (12oz) only.
• Leakproof Lid (1.0 and 2.0): Commuter Cups (8oz, 12oz and 16oz) only.
• Leakproof Lid 2.0 for 20oz: 20oz Leakproof Straw Cup only.
• Hydrate+ Extensions: Commuter Cups (8oz, 12oz and 16oz) only.

Our Leakproof Lid 2.0 has the latest improved features:

• Lowered the flipping angle so it no longer touches your nose.
• Adjusted spout feature that creates a more concentrated and smoother liquid flow.
• The stepped spout design allows lips to lock onto the spout, enabling smoother, more controlled sipping.
• Curved interior design that reduces dead corners for easy cleaning and lowers the risk of dirt buildup.

The previous Leakproof 1.0 has a lower spout position, with a silicone spout that touches the nose when the lid is flipped. It also has a more dispersed spout structure, resulting in a slower, inconsistent flow. The 1.0 has a wider spout, causing liquid to spill down it when drinking. The 1.0 also has more interior dead corners, making it harder to clean and more prone to dirt buildup.

Our original Splashproof lid is a press-fit lid meant for Omni & Splashproof cups and is not compatible with the new Commuter Cups, which have screw threads. Splashproof lids come with a slide lid.

Note: We no longer produce both Splashproof Lids and Leakproof Lid 1.0.

Hydrate+ extensions are an extension base that comes with two types of caps: a sports cap (with a straw) and a hydration cap, which can turn any of your Commuter Cups (8oz, 12oz and 16oz only) into a hydration bottle.

Hydrate+ extensions add an additional 5oz to your beverage when assembled onto your Commuter Cups.

Remove the original lid from the Commuter Cups (8oz, 12oz or 16oz) and screw in the extension base. Choose between the sports cap and the hydration cap.

Hand wash the cup as usual. Clean the base and caps with a soft sponge and a straw brush for straws. Hydrate+ extensions are dishwasher-safe (top rack recommended). Avoid microwaving, freezing, soaking in boiling water or exposure to direct heat, flames or sudden temperature changes.

Yes, the coloured versions of Leakproof Lids 2.0 and Hydrate+ extensions carry the same core features. The coloured versions are designed for personalisation and customisation to your liking.
