The cold-or-refund guarantee

Thirty days, used, fully refundable.

Use the tin in normal daily conditions for 30 days. If it does not hold pouches noticeably colder for the length of a working shift, return it for a full refund with return shipping paid. There is no requirement that it be unused or in its original packaging — the guarantee exists so the product can be tested properly. The lifetime warranty on the shell applies regardless.

Opened Chillcore packs are not returnable, as a gel pack that has been frozen cannot be resold. All other items are refundable in full.
