Old watch parts, vintage watch parts....all packages will be different. There are lots of little gears and stems and bits from the old watches. What I love about these lots is they are legit, not stamped out pieces that have been imported. All weigh 50 grams and are parted out equally. Each is a great surprise of cool useful stuff! The photo is *representative* as each assortment will vary. Comes in a nice plastic This is a nice buy....get 'em while I've got 'em!
