This box has space to hold 6 paperclips/small SD cards, 2 Large SD, 3 USB devices, Pens, pencils, markers, Etc. 1 ruler, and 3 small objects Eg. Erasers, lead replacement boxes...

I also included the older version I made which has 2 tiny holes for Sim cards but these DO NOT WORK. the bottom Large SD card slot DOES NOT WORK, and the older version doesn't have a ruler holder nor does it have eraser shelves.
