冰磚 - 零食收納盒

I was skeptical about the thermal claims, but my sandwich bread was still perfectly dry at lunch after packing it with two of these bricks. They freeze solid fast and don’t leak any condensation, which is my biggest pet peeve with ice packs.

My salads actually stayed crisp all afternoon after I put one of these frozen bricks on top. The way it chills quickly in the freezer and holds the cold for hours is exactly what I needed for packed lunches.

I packed one of these bricks with my lunch at 6am and by noon my chicken salad was still fridge-cold. The flat shape slides right into my bag without taking up too much space.
