Elegant key holder with shimmering crystals. Features iconic Louis Vuitton charm. Perfect for adding luxury to your keys or use as a bag tag Due to the fact that these charms are from a variety of luxury items, I am unsure of the material each charm is made of. Also, since these charms have been removed from their original state, a COA cannot be provided! However, almost all of these charms are double sided or stamped on the back For this reason these items do not have a COA and cannot be authenticated. A lot of the hardware comes from bag charms so those are not made to be showered with just as you wouldn't put your expensive bag in the shower, so it's best not to get charms wet
