Very rare and hard to get hold of.. sold out everywhere.
Its a replica of the locket (with moodstone) that the sirènes wear in the TV montrer H2o Just add Water and is an official licensed product.
The collier is great quality. It is a highly polished stainless steel collier that looks like silver. The locket opens and has three pictures of the sirènes to put inside (or toi can use your own photo).
