Alphabet - a - z plus ?. Includes nice little organizer. Imprint on metal, or metal clay (before or after firing), polymer clay (before baking). 27 pieces. Instructions on back of package, in case you can't figure out how to hit something with a hammer. A nice touch is that you hold the punch with your thumb over the logo on the side, you always place the letter right side up. However, they do NOT have the actual letter written on the side, so I suggest that you immediately take a sharpie and write the letter on the side to save yourself grief later. Unless you are the sort of person that uses something and immediately puts it away. In which case, there is no hope for you. If you buy multiple sets, you'll want to mark them to differentiate them too - so you don't accidentally mix up the type faces. Feel free to do it on purpose though.
