Purchased last year from a general goods and clothing store in Ikebukuro. I think it can be used unisex. The left one is a double strand, and the right one is a single strand. They look great when worn together. The length of the right one, measured with the clasp as shown in the photo, is approximately 50cm, and the left double strand is approximately 43cm using the same measurement method. I liked them, so there is some slight dullness and some signs of use. Please refrain from purchasing if you are looking for something in new condition. Only those who understand that these are used items, please. *No individual sales or price reductions, please. #ArtistVelvetCloset
