Review on Skyview 2Pcs 4 Game Memory Card Protection Hard Case Nintendo 3DSLL Game Cartridge Holders Storage SD Case Organizing Switch Games Card by Michael Mendoza

The term SD card to me means the "Secure Digital" memory card used in cameras and other devices. To check this, just search "sd card" in Wikipedia. Apparently, there's some sort of gaming memory card that's very similar in size and appearance, but a regular SD card won't fit in this case - the slot is too narrow by about 3mm. Too bad, this case would be perfect for my purpose. Of course, if you're getting this for the intended style of gaming memory card, then you should ignore this review.
