Thank you for viewing! This is a handmade necklace I purchased over 10 years ago at a general goods store. I believe it uses antique beads from overseas, Czech beads, etc., but I don't know the details... As it is a handmade item, it may not be as strong as commercially available products. Also, please consider purchasing only if you understand that it is an item that has aged and has been in someone else's hands once. I don't think it is compatible with metal allergies. Please be careful. ■Specifications■ Material... Czech beads, overseas antique beads, etc. (mainly from Europe) ■Shipping Method■ It will be placed in a zippered bag, wrapped in bubble wrap, and shipped via Nekopos. I loved this atmosphere at the time and went to the store frequently, but my tastes have changed and I haven't worn it, so I've kept it stored away. I would be happy to sell it to someone who loves the unique charm of handmade accessories or who likes the atmosphere♪
