Most:
Practice.
Aesthetics, friendly faux leather.
Well padded, well protects the memory cards.
Perfect closure thanks to its velcro system.
Cons:
Delivery time a little long.
For info:
This portfolio is scheduled for four memory cards (two on each side), but ...
Personally, i currently 5 SD memory cards and so on one of the sides, I have the proper scrappy sewing threads of a storage center.
Result, on one side, I can now store four cards in a vertical or horizontal position three.
In short:
As for me, my SD cards are tidy and protected in a portfolio that firm.
So happy with my purchase and I recommend this product.
