20オンス ステンレス製キャリータンブラー（ポップアップストロー付き） SX-MA60H

I was skeptical about the pop-up straw, but it seals tight and doesn’t leak in my bag. The 20 oz size is just right for a long commute, and it keeps my iced coffee cold for hours.

The handle makes it so easy to grab one-handed while I’m juggling my keys and lunch bag, and the pop-up straw seals tight enough that not a single drop leaked in my gym bag. Ice from my morning coffee was still clinking around at 4 p.m., which honestly surprised me.

I use this tumbler for my morning iced coffee, and the built-in handle makes carrying it to the car much easier. The vacuum insulation keeps my drink cold for a few hours, though I wish the lid sealed a bit tighter to prevent spills.
