Basically a Rotisserie for Tumbler personalizing! After placing decals or pictures, makers generally apply epoxy and this helps epoxy to spread evenly and then spins for the 7 to nine hrs it requires to dry! The total length is 12 to 15 inches in length and usually 6 inches in height and 6 inches in width! I will place two styrofoam "footballs" that fit the tumblers perfectly and can slide on and off the rod that rotates! The fit is snug so that the cup rotates evenly without moving or jumping! One football is larger for larger tumblers and a smaller football for the smaller mugs, tumblers or glasses being made!
