Mushroom Glass Tumbler with Bamboo Lid & Glass Straw — 420ml Borosilicate Aesthetic Coffee Cup | Ribbed Smoked Grey, Non-Toxic & Lead-Free

Your drink deserves a glass as interesting as what's inside it.

The Crockwitty Mushroom Glass Tumbler is the aesthetic borosilicate cup that has taken over coffee counters, WFH desks, and Instagram feeds — and for good reason. The distinctive mushroom silhouette, with its flared mid-waist, bulbous base, and satisfying vertical ribbing, makes this the most visually striking tumbler in any room it occupies. Whether filled with a golden iced latte, a green matcha, a creamy cold brew, or a fruit smoothie — every drink looks better in this glass.

BUILT ON BOROSILICATE — NOT ORDINARY GLASS

Not all glass is equal. The Crockwitty mushroom tumbler is crafted from high-borosilicate glass — the same material used in laboratory glassware and premium café cups. Borosilicate is significantly stronger than regular soda-lime glass, resistant to thermal shock (hot to cold transitions), highly chip-resistant, and completely non-toxic and lead-free. It does not absorb flavours or odours, meaning your morning coffee and afternoon smoothie taste exactly as they should — clean and pure.

THE BAMBOO LID — FUNCTIONALITY MEETS AESTHETIC

The natural bamboo lid is more than decorative. Its food-grade silicone gasket creates a secure, leak-resistant seal around the straw hole, protecting your bag and desk from spills. The bamboo grain and warm tones pair beautifully with the smoked grey glass — an aesthetic combination that feels premium without trying too hard.

THE GLASS STRAW — ECO-FIRST DRINKING

The included bent borosilicate glass straw fits flush through the bamboo lid and delivers a clean, reusable alternative to single-use plastic. It's sturdy enough for daily use and easy to clean with any standard straw brush.
