This SD card case can hold up to 4 SD cards. There are cut-outs in the corners for the magnetic cover, each side requires four 5x1mm magnets or 5x2mm magnets. The measurements are 69 x 90 mm and the case is only 7.5 mm thick.

Tolerances

• magnet holes: 0,3mm
• SD cards: 0,5mm

For people who mostly work with micro SD cards, I also have a model with four micro SD cards and one normal SD card in the same low profile design.
