Instant purchase is welcome. This is a handmade item by an amateur. The largest bead is 10mm Advanced Crystal. Total length (excluding lobster clasp and eyeglass strap): approximately 60cm Lobster clasp: 1.4cm Eyeglass strap: 2cm Small round (2mm) beads are used. Metal fittings: Silver Eyeglass chain Removing the eyeglass holders also makes it a mask chain. This eyeglass strap fitting can be attached to cordless earphones to use as an earphone strap, making it a multi-functional strap. I also sell mask straps and other accessories, so please take a look if you'd like. I carefully make each one with care, but I appreciate your understanding of handmade items by an amateur. #mask #glasses #glass #holder #eyeglasscord #eyeglassstrap #cord #eyeglasschain #chain #earphonestrap #glasscord #Korea #glassstrap #strap #beads #neckstrap #handmade
