Seeking a little box to put my PS Vita games and can take them easily, I was hesitant to buy it because of a comment saying it was difficult to leave the game cartridges. But considering the price, I did not hesitate for long. And I do not regret my purchase. A very good quality / price ratio. The cartridges tight fit, maintained by very flexible tongues. A small support in the same size as a cartridge can accommodate two Vita memory cards, but suddenly it takes the place of a cartridge and it will remain 7 slots for games instead of 8.
As I did not see the dimensions in the product description, here they are for those interested: 109x48x10mm (length, width, thickness).
