I'm a guy, Ok, who works with my hands on mechanical things. So my nails aren't manicured, in fact I cut them as short as I can or they get torn off in the mechanical things I do (5 motorcycles, 3 trucks, metal fabrication equipment, etc). But it was my sister's birthday and I wanted to use these to put a crank message on a toilet seat top (inside joke) for her. There were lots of sheets of these letters, in different colors, which was great. but STARTING each and every letter's RELEASE from the page they were adhered to was not at all an easy task. The material that the letters were made of are VERY, VERY THIN, so once a letter's corner is initially PICKED AT to begin release, often they would kind of ball up and had to be discarded. Each actual letter visually on each sheet APPEARS to be slightly larger/fatter than it actually is, so beginning the picking at it was kind of a guess where to start; some folding of the letter on the page kind of helped to find an actual corner of a letter, like a K as example. But tons of letters, numbers and sheet after sheet of colors. Great value, but my advice is only buy if you've got sharp finger nails.
