Very good storage box. Looks very strong, with the edges of the hard plastic box (top and bottom, through which we see the cartridges and a softer plastic, less solid on impact if something falls on it) Size level, compared to a DS lite: 1 cm less in length, 1 cm more in width, 0.5 cm more in height. The storage space, much like a book, it opens and has 2 removable compartmentalized to the middle as 2 pages, each side 6 storage for games: 6 + 6 + 6 and 6, so 24. The games are clipped in housing, the clips have asses looks solid, the cartridges do not move once clipped.
Conclusion: a very good investment to put your DS cartridges
