This is a basic holder that slides onto the end of the playmat [ you will need two, one for each end] to protect the playmat and its edges when not in use. 

The gap for the playmat to ‘slot’ into is 9mm, this will fit all standard Pokémon playmats found in collection boxes as well as Ultra Pro playmats. 

This means the playmat won't have any of those annoying rubber band marks and it should help to keep its shape.
