This is a 1017 ALYX 9SM Dual Chunky Keychain Necklace. ※Defective ※The clasp that fastens the necklace is broken, so it does not function as a necklace in its current state. It should work without any problems if you can replace the connection. If you wish to purchase, please be sure to comment (^o^) All items I sell are authentic.
