Poltex's own unique design.  Visually manage glove box stock (3 or 4 boxes) to make sure to never be left empty handed.  Designed to hold 3 or 4 boxes of the same size glove:  2 or 3 backup and one in use.  When the bottom box is empty, simply lift the sliding face plate up, pull out the empty box, and a full box drops down to "in use" position.
