This little box of emory boards fits into the smallest space. I stash them everywhere. - 6 little files in a 2 inch by 1 inch bvy 1/4 inch thick box - I am never without an emory board anymore. The long ones used to get bent or they come in those cardboard backed plastic bubbles that let the boards all fall out. These have a little pink and white box like a matchbox so they never fall out, never get bent, dont't get damp if the box gets slightly rained upon and last for ages.
