...that looks like and old box. I've had that Dremel so long that I'm not really sure how old it is. It came in a plastic box, but that box's clasps broke and fell off years ago, and I've been keeping it shut with rubber bands.
The new box is made from wood reclaimed from pallets I got for free. I sanded it lightly, but left the original saw marks and nail holes. The upper right compartment has a very high tech "block of wood with holes in it", for organizing bits.
