Description

A Mug That Makes Heat Feel Effortless

Some mugs simply hold drink; this one elevates experience. Double-wall borosilicate glass creates quiet buffer between warmth and touch, keeping beverage hot while hands remain comfortably cool. Transparent silhouette gives coffee floating presence - soft, suspended glow that turns every sip into small visual ritual.

300ml - generous everyday mug size - with double wall protection.

Whether it's morning espresso, afternoon tea or chilled brew, mug brings clarity, comfort and calm to daily routine.

Designed for Temperature, Comfort and Everyday Rhythm

Insulated double wall maintains heat longer and prevents condensation, making it ideal for both hot and cold drinks. Outer surface stays cool, supporting steady grip even with freshly brewed coffee. Made from high-borosilicate glass, withstands thermal shock from –20°C to 150°C, ensuring durability for daily use.

Comes with a comfortable handle, so you can hold it with ease even when freshly poured - the double wall keeps the outer surface cool regardless.

Its clean, minimalist shape blends naturally into any coffee setup - from modern bar to quiet home workspace.

Clear Glass

Mug feels light, smooth and cool in hand. Drink inside stays warm, steady and comforting. Floating effect gives each beverage bright, clean, elegant presence. Every sip feels intentional, calm and visually centered.

Double wall = anti-scald technology, so the handle stays comfortable even with hot drinks.

Why It Belongs in Ritual

This mug merges comfort with clarity. Double-wall insulation protects hands, borosilicate glass preserves temperature, and transparent design highlights colour and texture of drink. Eco-friendly, food-safe and crafted for people who appreciate tools that feel simple, refined and quietly expressive.

Difference vs Versatile Double Wall 200ml: This is 300ml, 50% bigger, generous everyday mug. Vs Comfort 250ml Handle: This is 300ml with a cleaner silhouette, CE certified.

Our Tip

For more stable temperature, warm mug with splash of hot water before serving. Enhances heat retention and makes floating effect even more striking. Works amazing for iced coffee - no sweaty hands.
