保冷剤

I've been using this in my kid's lunchbox and it keeps their yogurt cold until lunchtime without any mess. The gel inside stays pliable even after a full night in the freezer, which makes it easy to fit around their water bottle.

The non-toxic fluid inside gives me peace of mind since it sits right next to my kid's yogurt. I froze it overnight as the instructions say, and by the time we hit the park bench at noon, everything was still properly chilled.

I’ve been using this ice pack in my kid’s lunchbox every day, and it keeps his yogurt and apple slices cold until lunch. The non‑toxic fluid makes me feel better about it being inside his bag. It’s nice that I just freeze it the night before and it’s ready to go in the morning.
