Multi-purpose 60-hour Heat Pack (2 Pack)

Be careful using this in an insulated box. It kept it warm but a little too much, as it killed the plants I shipped out. But it did its job, and for that I give it 5 stars!

Very reliable heating source for animals

Heater can reach more than 80 degrees so be careful if packaging in a small container. Heat packs worked perfectly for a 6 hour drive. Discus made the trip nice and warm.

These are amazing! They saved my plants when moving across the country during the cold season. Kept them warm for a couple days, I'm very impressed! These are a must for winter transportation!

I shipped fish, plants, and snails during the coldest months of the year from the west coast, and they all arrived to their destinations in the east coast healthy and thriving. My only complaint is that the price was a little elevated unless you bought a large pack of them, which I didn’t need at the time.
