Not that it's hard to find these boxes organisers here in Brazil. I think any stationery store has. But this below has 36 positions and each of them can be expanded or modified. It was interesting to organize the platelets of Arduin I have purchased.
Is not too large, has only 27.5 cm x 17.5 cm.
Each of the horizontal divisions may be withdrawn, so if you have something bigger to save magazines easily can unite.
Below is a part of my collection and PIC Arduino parts.
A good product, Although I think, for the photos, It was much bigger. I still think it was worth the price to have adjustable divisions. I leave the link to the product:
