Our gel packs were not designed to be used on open wounds.
No, please discard your pack if it breaks.
The beads in your pack will eventually start to break down after a while. This is perfectly normal, and your pack will still work even after all the beads break down.
You can leave your pack in the freezer indefinitely, or just chill it for a short period of time. Some of our customers are looking for “cool” rather than “brrr” so they store their packs in the fridge,
Even microwaves with the same power often heat differently, and sometimes unevenly. We always recommend that you test your pack temperature before you remove it from the microwave, and if it seems to be unevenly heated, shake it around for a while to let the pearls mix together.
