Prima box for memory cards

I bought this box, so I can create my different memory cards with songs for various purposes. So for example I have also created an individual for my work with children a memory card for my sports groups (children and youth) more memory cards and for my hobby dancing. When I then with my Musicman (these little cubes for listening to music) for example in the gym or anywhere else'm getting, I have the memory card good at hand. The box is very stable and compact, the cards are kept safe in it and I do not have to look far, because now where is this or that card. Also you have the same adapter cards on hand when the PC once more want to add more songs, or want to hold other content to a memory card at work. The only downside: Despite the small bulges, it is not quite so simple the card out of the box to get out. But better it goes harder than me if all the cards meet the same when opened.
The delivery was fast and good.
