This is for one Cricut 12" x 12" cutting mat and Universal Keypad Overlay set only.
The Universal Keypad Overlay is a must for the new smaller cartridges that use one overlay for any of the cartridges. The booklet that comes with the cartridge is your guide to which buttons to push to get the font or design that you are looking to cut out. 
These two items are brand new. However, they do not come with packaging. Cricut no longer makes them and they are hard to find.
