First, there is no chain. So make sure it's what you want when you buy it. It's more like a car key. Can be used with a heavy duty chain but has some weight so don't buy anything flimsy or flimsy if you are. There were no instructions included. Mine arrived late (which I might be overlooking) but it took me 3 days to figure out how to open the damn thing without resorting to hand tools that I was afraid would ruin a very clean finish. Basically, take the D-ring that is welded to the back and twist it. I resisted this because it doesn't look very strong and I was afraid I would break off the D-ring at the base. All this aside. it's still a good thing. It comes clean, the script is deeply engraved so it shouldn't go away for years to come. The cleaning is well done, the device is heavy, with good sealing. Be sure to apply some glue to the threads before resealing (many states require this for containers and urn devices).
