We have a limited quantity of our Medium Mystery Boxes available! What are Mystery Boxes? Over the years, we collect a lot of stuff. Leftovers from prototyping, extra parts from kits, damaged items, returned items, old stock, samples, incorrectly order parts, and numerous other things that just take up space. Rather than recycle all this stuff or leave it on a shelf to take up space, we make mystery boxes for those that want to restock their spare parts bin. Available while supplies last!
