This item includes everything you need to make 500 magnets using thick PHOTO paper stock and a photo machine and photo graphic punch:
The mylar on these sets is larger than our standard 2"x3" mylar in that it gives more wrap-around on thick photo stock paper from a photo lab (or die-sublimation prints). These parts will only work with a photo-button machine and will not fit into a standard paper machine. The magnets, metal shells, and plastic backs are the same as those found with standard 2x3 magnet sets.
Actual mylar dimensions: 2.894"H x 3.892"W
Thickness: .003 (3 MIL)
