How thick are your magnets?
Our custom magnets are 15 mils (381 microns) thick. With laminate and coating, the total thickness is 19 mils (482 microns).
Keep in mind, mil is not short for millimeter. Mil is a commonly used measurement for products like magnets and stickers.
For reference, our vinyl stickers are 6 mil thick (0.006 inches or 152 microns). When still on the paper backing, our stickers are 15 mil thick (0.015 inches or 381 microns).
