แก้วชาคู่ผนัง

I was worried the glass would feel fragile, but it’s surprisingly sturdy and the double walls really do keep my tea hot while the outside stays cool to the touch. Watching the tea steep through the clear glass is oddly calming, and it cleans up easily with a quick rinse since nothing sticks to it.

The 350ml size is just right for a single generous brew, and the glass stays cool to the touch even with boiling water inside. I love watching the tea steep through the clear walls—it makes the whole ritual feel more special. Only downside is hand washing, but it's quick enough.

The double-wall design actually works—my tea stays hot while the outside stays cool enough to hold comfortably without a sleeve. At 350 ml it's just right for a solo afternoon steep, and watching the leaves unfurl through the clear glass makes the whole ritual feel more special.
