It's official!! Insert Here is an official supplier for the Plaid Hat Games Mice & Mystics line of board games. This insert will fit the base game and the "Heart of Glorm" expansion - along with the mini expansions "Cat's Cradle" and "The Ghost of Castle Andon". The insert is designed to hold sleeved cards. This, newer, design features the finger slots for cards on the outside of the insert making card removal much easier.
