Instructions for use


​FishBellies are hot-or-cold healing

packs filled with extra-clean, non popping, large-kernel corn. To ensure your safety and help your FishBellie last for years to come, please follow our instructions carefully!

For cold therapy, simply place your FishBellie in the freezer for 1-2 hours.


For heating pad therapy, warm up your Big and Little FishBellies in the microwave for 1-2 minutes, adding 30-second intervals as needed. Guppies only need 30 seconds! 

More detailed instructions are included with each order. 



FishBellies are great for kid boo-boos, but only for children ages 6 and up. FishBellies are not for babies! Adult supervision is always required.

Do not use FishBellies on numb body parts,

as this can cause serious injury. 

Do not store in extreme heat or humidity,

as natural corn contents could spoil. 


Only heat FishBellies in microwaves

WITH A TURNTABLE. This ensures that heat is distributed evenly, preventing damage or hot spots on your FishBellie. Be sure to FOLD THE TAIL UNDER YOUR FISHBELLIE as it heats up,

so that the turntable can rotate freely.

Never leave your FishBellie in the microwave unattended. 

Be extra-careful the first time you heat up

your FishBellie, as every microwave is a little different. We suggest massaging your FishBellie a bit halfway through heating to ensure that warmth is distributed evenly.

DO NOT put FishBellies in the oven!


When freezing your FishBellies, place them

in a plastic bag to protect them from food odors.
