All of our magnets are made from tin-coated steel wrapped over a steel backer and an circular magnetic sheet. The designs in front are wrapped in a glossy, protective mylar. Overall magnet dimensions are 2.25" round. These magnets make perfect impulse buy options to stage at the cash wraps and POS areas. Great for accessorizing and livening up the kitchen refrigerator, office file cabinet, home bar area, garage, toolbox, man/babe cave or galactic service droid! *Made in the USA* All items are made on-demand as orders are placed, so no design will ever be out of stock. *Any pop-culture references used on these designs are intended as good natured parody and satire so please take it as such.
