Adhesive box 'SLIP-IN BOX' that can be used without a magnet.

The "SLIP-IN BOX" is a type of box that achieves a structure for closing the lid by sliding the tip of the triangular lid into a slight gap at the bottom of the main body (SLIP-IN). It fulfills the structure and function of the lid entirely with paper, without using magnets, and is an original product made with our unique technology that can be mass-produced.
