Lot of 30 tubes like shown. Here is the deal, we have dozens of these. I can usually find a way to repurpose everything, but these have me a bit stumped as to what else they can be used for, but I am sure they are handy for something. We welcome ideas!!! Of course you can use for the intended purpose which originally was to ship electronic circuit board edge connectors. You can also store/ship other components, ICs, transistors, etc, but may have to add some padding, paper etc, so they do not move around. Buy a box, find a new use, share it with us, and your next box is 50% off listing price! Crafts, mailing storage of long cigar shaped items, drill bits, thin tubes, thermometers, fluorescent tubes, copier bulbs, etc store stacks of buttons, garden seeds, beads Each tube includes the rubber end plugs as shown on each end, which are a soft rubbery type material. 24" long see picts for other dimensions approx 1" square but with an L shape to it. Color is sort of a smoked clear look. Condition is basically new, they had new surplus connectors in them , we have removed the connectors and pushed the end cap back in.
