Thank you for viewing! This is a set of 13 cute black-themed mask charms. The lobster clasps are small, approximately 10mm in size. Please refer to the second photo for the size of each charm. This is a handmade item. I make each one with care, but as a handmade item by an amateur, there may be minor scratches, stains, or other imperfections. Please understand that we cannot guarantee against breakage or defects due to the nature of amateur work. There may be slight color differences between the photos and the actual product. I try to match the colors of the parts as much as possible, but there may be some variations. The parts are imported from overseas, so there may be distortions, minor scratches, color unevenness, etc. Please refrain from purchasing if you are sensitive to imperfections or if you are looking for a perfect product. Delivery of regular mail on Saturdays, Sundays, and holidays has been discontinued. Even if shipped on Tuesday or Wednesday, delivery may be delayed until the following week. Please understand that it may take some time for delivery. m(_ _)m Color: Black-based
