Rishi × Miir オールデイ ストローカップ

It's been sitting in my car through a 90-degree afternoon and the ice cubes are still there, which is honestly more than I expected from any cup. The double-wall insulation makes a real difference, and I love that the body is made from recycled materials without feeling flimsy at all.

The lid seals tight enough that I can toss it in my bag without worrying, and my iced tea still had ice cubes floating around after a full workday. I’ve been reaching for it every morning since it arrived.

The double-wall insulation really does the job—my iced tea stays cold through a whole afternoon of errands, not just the first hour. The straw lid seals tight enough that I can toss it in my bag without worrying about spills, which is the main reason I grabbed it.
