稜鏡能量咖啡

I wasn’t expecting the lid to seal so snugly, but it does—no drips even when I tossed the 30oz in my bag on the way to work. The clear straw’s a nice touch for cold drinks, and the cup itself keeps my iced coffee cold for hours. Hand washing is a bit of a hassle, but the size and durability make it

The 20oz size fits perfectly in my car cup holder, and the lid seals tight enough that not a drop spilled on my commute. I've been using it for both my morning iced coffee and afternoon tea, and the clear straw makes it easy to see what's inside.

Took this 30oz to work and it kept my iced coffee cold through a full shift—the clear straw and lid make it easy to sip while typing. Hand washing is a minor hassle but the size and heat/cold versatility make it worth it.
