Crockwitty Double Wall Glass Mug Set of 2 — 250ml Borosilicate Glass Tea & Coffee Cups | Ergonomic Handle | Lightweight | Thermal Insulation

There is something quietly magical about a double-wall glass mug. Pour your morning chai, your green tea, or your cold brew — and watch the liquid appear to float, suspended in a glass bubble, completely untouched by the outer wall. The Crockwitty Double Wall Borosilicate Glass Mug Set of 2 turns your everyday drink into a moment worth pausing for. And it keeps it at the perfect temperature while you do.

The double-wall construction creates a sealed air pocket between the inner and outer glass walls. This air gap acts as a thermal insulator — slowing heat transfer in both directions. Hot drinks stay hot longer. Cold drinks stay cold without forming condensation on the outside. Your hand stays comfortable at any temperature. It is the same principle used in vacuum flasks, but in a form that lets you see and appreciate every layer of your drink.

Premium Borosilicate Glass — Made from laboratory-grade borosilicate glass, the same material used in scientific equipment and professional barware. Borosilicate is stronger, lighter, and more thermally stable than standard glass — it handles temperature shifts without cracking and resists staining from tea tannins and coffee oils.

Double-Wall Thermal Insulation — The sealed air gap between the two glass walls keeps hot beverages hot and cold beverages cold significantly longer than a standard single-wall glass. No more burning fingers. No more condensation rings on your table.

Ergonomic Loop Handle — The clean, generously sized loop handle is designed for a confident, comfortable grip. Wide enough for all hand sizes. Sturdy enough for daily use. Elegant enough for guests.

The Floating Liquid Effect — The transparent double-wall creates a stunning optical illusion — your tea, coffee, or juice appears to float inside the glass, untethered from the outer wall. Arguably the most photogenic mug you can own. Every flat lay, every morning post, every gifted set gets photographed.

Lightweight & Durable Build — Despite the double-wall construction, these mugs are remarkably lightweight. The borosilicate glass is chip-resistant and built for the rigours of daily use — not a delicate display piece, but a hard-working everyday mug that happens to be beautiful.

Generous 250ml Capacity — Perfect for a full cup of chai, a standard espresso-based drink, a green tea serving, or a small hot chocolate. At 9.5cm tall and 8cm diameter, these sit comfortably on any tray, in any cup holder, on any shelf.

Perfect for: masala chai, green tea, black tea, Darjeeling, filter coffee, espresso, Americano, hot chocolate, matcha latte, golden milk / haldi doodh, cold brew, iced tea, and any beverage you want to savour slowly. A go-to gift for chai lovers, coffee enthusiasts, minimalist home décor fans, Diwali gifting, housewarmings, birthdays, and new home celebrations. Pairs beautifully with Crockwitty's tea sets, glass water pitchers, and serving platters.

Hand wash only — gently clean with mild soap and warm water. Use a soft cloth or sponge only. Do not use abrasive cleaners or metal scrubbers — these will scratch the glass surface. Not dishwasher safe — the high heat and harsh detergents will degrade the seal between the double walls over time. Not microwave safe — the double-wall air pocket is not designed for microwave heating. Avoid sudden extreme temperature changes — do not pour boiling water directly from a kettle into a cold mug; allow the mug to warm slightly first. With proper care, these mugs will retain their clarity and double-wall seal for years.

Nestasia makes beautiful double-wall mugs — but their Amazon reviews consistently flag one concern: fragility. Multiple buyers describe them as "delicate" and "thin." The Crockwitty Double Wall Mug Set prioritises durability alongside beauty — thicker borosilicate construction, a sturdier ergonomic handle, and a clean, classic design that works in any kitchen without the anxiety of breakage. Same premium double-wall experience. More confidence in daily use.
