You can heat your FixIts however you want, but we recommend using water. So just heat some water to up to 60 ºC, insert the part of your FixIts you want to mold inside and mold it while it's hot. Once it cools it will harden. It doesn't act as glue, but it does attach very well to itself as well as fabrics, some plastics, and other wrinkled surfaces. You can use it to fix wires, zips, use it as a valve lid on a tire or just mold it into anything you want. The limit is your imagination and the possibilities are endless! If that's not enough, you can allways re-heat it and re-mold it into the shape you want, being immortal.
The FixIts products don't expire and are non toxic, making them suitable for everyone.
