The silicone ice pack comes with a silicone gasket to prevent condensation, and its stainless steel case prevents water from leaking from the pack, making it easy to carry.

These ice packs are ideal for a wide range of uses, from watching sports, commuting, and everyday use to prevent heatstroke. Because they retain their coldness for a long time, they're also great for use as an ice pack while shopping, icing after sports injuries, and helping to reduce fevers. [Can be used in both summer and winter] This eco-friendly product can be used year-round as an ice pack in summer and a hot water bottle in winter.

[Long-lasting storage] Mini ice packs can be used in two ways: by adding ice water directly or by adding water and freezing it completely. The longer you leave the freezer on midsummer mode, the less likely it will melt. The length of time you freeze the ice packs and the temperature of the freezer are also important factors in determining how long they will last.
