Unisex, can be used by both men and women. I received this new from a friend and have kept it stored ever since. There is no box. I heard this was a non-sale item given only to a limited number of people. This item is said to have been received as an invitation to the final party announcing the closure of CELUX, a members-only salon operated by the Louis Vuitton Japan group, which closed on March 31, 2008. Can be used in 2 ways (choker or double-wrap bracelet). Size: Approximately 44cm X Approximately 1.8cm Damier Shipping costs will be covered by me.
