Matchbox Pendant composed of 2 parts-- the metal exterior casing seen here, and the polished colored drawer.* After the drawer is slid into the metal exterior, a chain or cord is strung through the holes. This not only is the method to hang the pendant but acts as a stop for the drawer so it doesn't slide all the way out. This pendant is great for keeping a small photo or printed message. The depth also allows for something small (and thin) to be stored there as well. Or you can just wear it empty.
*Important- This listing is only for the metal exterior. You must also buy the drawer in your choice of colors here: Drawer for Metal only
The chain of course is not included but you can easily add your own cord or chain (black rubber, leather, satin, gunmetal, etc). I recommend not going with anything larger than 2mm to make sure it slides through easily. If you would like to add a finished chain (with a clasp) here are a few on Amazon that should work:
2mm Black Leather Cord with clasp 2mm Black Rubber Cord with clasp
Just be sure that the loop end of the necklace is no larger than 2mm so that it slides through the holes easily.
