Thank you for viewing! This is a set of 5 pairs of stone-embellished goldfish mask charms in 5 colors. A set of 5 colors, one of each color, is also available for 599 yen. The lobster clasps are small, approximately 10mm in size. Please refer to the photos for the size and the back side. 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 provide a guarantee for damage or defects due to the nature of amateur work. There may be slight color differences between the photos and the actual product. I try my best to match the colors of the parts as closely as possible, but there may be slight 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 seek perfection. 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
