As of August 18th, 2021, these items ship only to the United States. Global shipping rates have skyrocketed and these heavy items can no longer be shipped worldwide.

Our hot and cold packs are hand made using whole kernel feed corn, a dense grain that holds heat and cold far better than rice or buckwheat.  They are shipped unscented, and smell pleasantly like fresh popcorn when heated.
