Only used once. The outer surface of it already got a bit of white colour when I brought it. It's performance is way better than its appearance.
Can pour hot boiling water into it BUT NOT boil it in the hot water or put it in the microwave.
Reusable ice bag
Just pour ice water into it.
How long it lasts? It is depending on the using condition and surrounding temperature. Under room temperature, it can last for 3-4 hours.
