This convertible box, large in size and extremely robust, contains two removable letter trays that can store up to 200 double-sleeved cards. The Stronghold model is lined on the outside with the elegant Nexofyber material, and on the inside, with a soft microfiber lining. It also contains a drawer for accessories. Like other convertible products, its flaps can be removed and attached to the back of the box. Its powerful magnets ensure a secure closure. The flaps and removable letter trays allow you to customize the box by combining the pieces to your liking.
