The Cup Your Whole Family Will Reach For.

Upgrade your daily hydration with a cup that is built to last. Our 350ml Stainless Steel Cup is the perfect step up from baby cups, bridging the gap between "kids' drinkware" and "grown-up essentials."

Crafted from thicker, premium-grade 18/8 stainless steel, this cup has a reassuring weight and durability that cheap reusables just can't match. It features a matte-finish exterior and an electropolished interior for a clean, metallic-free taste.

Designed for Grip & Style: The colourful silicone band acts as a secure, non-slip grip for little hands to hold with confidence. Available in four vibrant colours, the bands make it easy to colour-code drinks for siblings or guests—no more arguments about whose cup is whose!

Whether it’s for a toddler’s smoothie, a school kid’s water, or a cold juice by the pool, this is the unbreakable essential for eco-conscious families.

At a Glance:
✦ Secure Grip – The silicone band helps little hands hold tight.
✦ No More Mix-Ups – Bright colours help kids (and adults) identify their own cup.
✦ Built for Life – Thicker, dent-resistant steel that is virtually unbreakable.
✦ Versatile Size – 350ml capacity is perfect for kids and adults.

Are your products certified?

Our highest priority is the safety and quality of our products. To ensure this, we engage independent labs to test our products to certify they are free from harmful chemicals like BPA, BPS, lead, and phthalates.

This testing verifies the integrity of our chosen materials: premium 18/8 (304) food-grade stainless steel and high-quality, platinum-cured silicone. We select these materials because they are renowned for their durability, non-toxic properties, and excellent performance, allowing us to provide practical and long-lasting options you can trust for your family. You can learn more about our quality & safety here.

Should I wash my stainless steel products before use?

Yes, we always recommend washing your stainless steel products before first use. Occasionally, you might notice some residue left over from the manufacturing and polishing process. A quick handwash with warm, soapy water or a cycle in the dishwasher will easily remove this, leaving your products spotless and ready for mealtime.

Can I use your stainless steel products in the microwave?

Most of our stainless steel products are not microwave-safe, as stainless steel can cause sparks and damage your microwave unless specifically designed for microwave use. However, our Tuffin Range food storage containers are microwave-safe. Please check the individual product description page for detailed usage and care instructions.

Yes. It is sized for kids 3+ and works great for teens and adults.

No. The electropolished interior resists odours and keeps flavours clean.

Is it dishwasher safe?

Can I use it for hot drinks?

Yes, but test the temperature first and use caution with children since steel conducts heat.

Is the silicone removable?
