The shallow, relatively small 'wallet for 8 + 4 (micro) SD cards is as an idea and of the production was very good. Absolutely bad, however, two things: a) the SD card must be inserted with the back to the front, so that you can see the printed side in the inserted state not see, and b) (much worse), me it was not possible to correct refer inserted card tray back, neither by gently grasping with fingernails, nor coarse pulling with tweezers, even by simply pushing out. The map was so firmly fixed that I could remove them only by destroying the support. Absolutely NO recommendation! I've now also risen for 8 cards a memory card protection box of Profox JJC. This is slightly thicker and heavier, but the cards are securely protected and can be taken without any problems!
