Lot of 10 Watch-Craft Red Plastic Pocket & Wrist Watch Movement Holders

Lot of Eleven Watch-Craft Red plastic pocket and wrist watch movement holders from what looks like is for an 18s down to what looks like about 15/0s or thereabouts (~16.5mm). These are clearly used, some more so than others, with the 16s one looking to ave had the most use. Nevertheless they are all fully functional and the red makes them really easy to find on the bench. I have a set of these myself and am very fond of them and use them virtually every day. Images do an adequate job of representing the lot.
