리아스 그레모리

I've been using this tumbler every day for my iced coffee and the clear straw actually makes it easy to see how much I have left. It keeps things cold for hours, and while hand washing is a bit of a chore, the stainless steel holds up nicely.

The lid seals snugly enough that I can toss it in my bag without worrying about leaks, which is huge for me. I've been using it for hot tea in the mornings and the outside stays cool to the touch. Just remember it's hand-wash only, but that's a small trade-off for how well it works.

The steel keeps my iced coffee cold for hours without any condensation on the outside, and the clear straw is a nice touch for seeing what's inside. I’ve been using it daily for a week, and hand washing is quick enough that it doesn’t bother me.
