This is a custom made solid wooden deck vault. The box is designed to hold 100 Db sleeved cards or 120 Single sleeved cards. The other design feature includes a hidden sliding mitered top which blends in with the rest of the box and locks tight when shut. A pair of spline joints reinforce each of the corners and lock them tight together.  This particular deck vault has a window cut out to view your favorite MTG art.
 
The bottom panel is constructed from maple with Aaron Cain's logo
