Temperature Activated Color Changing Thermochromic Fabric Paint (2 oz Black Changing to Yellow at 77F/25C)

This product works as described but you have to know what you really want. I wanted something that would change right at body temperature. Figured 99 would work pretty good. Nope. Too much environmental effect. That was my mistake though. If you want it to change colors by touch you need to use one that transitions at a lower temperature.

A little goes a LOOONG way. This was great stuff to work with, easy to put on, very sharp dark color. The more layers of paint, the more grey when the color does change. Didn't work quite the way I wanted it to on the cook's aprons as I don't think they changed while they worked (which I don't get because that kitchen was easily over 100-degrees!) But it is still a really fun t-shirt feature.Also worked great for an escape room element- heated up with hand warmers really well

I'm a fashion design student currently using the black to colorless paint in my senior collection and it's awesome. The company is very friendly and quick to respond in inquiries. Would highly recommend!

Awesome ink! We used it in a puzzle room and it was a success. Worked well with a hair dryer, but breathing on it could work too.

I made a color changing coffee mug and I LOVE how it turned out. The best part is that I didn't have to bake, just air dried and it's dishwasher safe too.

Though it's expensive it is undeniably magical

Worked great for an art project

Worked great for a school project!
