Kitchables Glass Tea Cups Double Wall Borosilicate Glass Tea Cups, Pack of 4 Review (2026)

What it is

Kitchables' Glass Tea Cups are a set of four double wall borosilicate glass cups sized at 2.5 ounces, about 75 milliliters, each, which puts them closer to an espresso or small tasting cup size than a full mug. The double wall design traps a layer of air between an inner and outer glass wall, which is the mechanism that keeps the outside comfortable to hold even when the inside is filled with hot tea. Borosilicate glass is more resistant to thermal shock than standard glass, meaning it handles the temperature swing from hot liquid better without cracking, which is part of why it is a common choice for small insulated drinkware.

Capacity

Multiple retailer listings for this exact model list the capacity as 2.5 ounces per cup, so buyers can confirm ahead of time that these are small pour cups rather than full sized mugs, useful for gongfu style tea tasting or espresso rather than a big morning cup. That small size is worth planning around if the goal is a standard 8 to 12 ounce mug of tea, since several of these cups would be needed to match one regular sized mug. For gongfu brewing or sharing a pot among a few people in small pours, the 2.5 ounce size is actually a practical match rather than a limitation.

Materials and care

The borosilicate glass used here is described as scratch resistant and safe for both the microwave and the dishwasher, which is more convenient day to day than glassware that requires hand washing or air drying only. The double wall construction that keeps the outside cool to the touch also means there is a small sealed air gap between the two glass layers, so a cracked or chipped cup should be retired rather than kept in rotation, since a damaged seal can let moisture in over time. Clear glass throughout also makes it easy to see the tea's color while pouring.

Set size and value

A set of four cups covers a small group session or a couple sharing a pot, which matches how these cups are sized for tasting or gongfu pours rather than solo daily mugs. Because the cups are uniform and simple rather than decorated, they work well alongside a teapot or gaiwan as a matching set rather than as standalone gift pieces. Buyers wanting a single oversized mug for personal daily tea, rather than a shared set of smaller cups, would be better served by a different double wall product in a larger size, since stacking several of these small cups to match one mug is not practical.

Who should buy it

These cups suit anyone building out a gongfu or tasting style tea setup who wants a matching set of small, heat safe glass cups rather than one oversized mug. They also work for espresso or small pours of any hot drink, given the microwave and dishwasher safe borosilicate construction. Buyers looking for a big single serving mug for daily tea drinking should look at Kitchables' larger double wall mugs instead, since at 2.5 ounces each, these cups are built for small, frequent pours rather than one large cup all at once.
