Review on MIKA3D Silicone Template Printing Accessories by Justin Guldin

This is a great product if you just starting out with a 3D pen. My daughter and I are learning how to use a 3D pen and this mat really helps create perfect squares, circles and even triangles because of the ridges. Or, if you just want hands-free, you can flip the mat over and use the smooth backing (not sure if that's on purpose lol). Finger guards are also nice (no pun intended) when you need to remove stubborn filament from a very hot tip. Overall very happy with this purchase.
