Thank you for viewing! This is a set of 4 mask charms featuring various cat designs. The lobster clasps are small, approximately 10mm in size. Please refer to the second photo for the size and the third photo for the back. 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 my best to match the colors of the parts, but there may be some variations. The parts are imported, 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, and even if shipped on Tuesdays or Wednesdays, delivery may be delayed until the following week.
