二重構造抹茶カップ

The froth stays perfectly silky on top while the matcha's deep green shows through crystal clear—it's like drinking from a tiny aquarium. I've been using it every morning for a week and the double wall actually keeps the heat off my fingers, which is a game changer.

I love how the borosilicate glass lets me see the vibrant green matcha and the froth settling, and the double walls actually keep my drink warm without burning my hands.

Didn't expect much but the borosilicate glass feels way sturdier than it looks, and watching the green swirl through the clear walls honestly makes the whole whisking ritual more fun. No fogging or condensation either, even with hot water.
