Rub-Ons or Transfers come in all shapes, sizes, and colors. They're sticky on the back side (like stickers), but they're applied with a stylus or a popsicle stick. The most popular form of Rub-Ons are alphabets. The first company to make Rub-Ons or Transfers popular was Making Memories, but almost every major player in the scrapbooking business is now coming out with their own alphabet Rub-Ons. The benefit to Rub-Ons over stickers is the fact that stickers often have an outside ring, where Rub-Ons have a very clean look. Often times, you can't even tell the difference between a Rub-On and a handwritten title.
