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 as this is an amateur creation, we cannot guarantee against breakage or defects. 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 these issues or if you are looking for a perfect product. Delivery by 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. Please be aware that it may take some time for delivery. Thank you for your understanding. m(_ _)m
