All in One Jumbo Sky 馬克杯

The filter is a nice touch, but honestly the double-wall insulation is the star. I can hold it comfortably while the tea steeps, and watching the color bloom through the glass is half the enjoyment.

I’d forgotten how nice it is to actually see the tea brewing—the double-wall glass keeps my fingers cool even with boiling water, and the silicone rim makes it easy to grip. The filter works great for loose leaf, and it’s become my go-to for slow weekend afternoons.

The stainless steel filter is perfectly fine for loose leaf teas, and I love how the double walls keep my hands cool while I watch the color of my brew steep.
