Review on 🎨 InstaMorph Pigment Pack: Enhance Your Moldable Plastic Creations! by Andrea Sloan

I've used them with both ThermoMorph and PolyMorph molding resin and they work great. I've managed to create custom colors that are almost identical to the ones I'm trying to customize. The only slight downside to this is that I've found that if I try to make a really dark/concentrated color and add a few colored granules to a small amount of white granules, after mixing the color, the resulting plastic (even after the reheating) becomes slightly harder and appears to cure faster than plastic without the addition of colorant.
