Thank you for viewing! This is a set of four pairs of monotone cat mask charms. Since they are pairs, you can wear them like earrings, on the back of your mask straps. They are cute worn with the same color on both sides, or with different colors on each side! The lobster clasps are small, about 10mm. Please see the photos for the size of the charms and the back side. This is a handmade item. I make them with care, but as a handmade item by an amateur, there may be imperfections such as small scratches or stains. Please understand that we cannot guarantee against breakage or defects as this is a handmade item. There may be slight differences in color between the photos and the actual product. I try to match the colors of the parts as much as possible, but there may be slight differences. The parts are imported, so there may be distortions, small scratches, color unevenness, etc. Please refrain from purchasing if you are sensitive to imperfections or are looking for perfection. Please note that 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. Thank you for your understanding regarding the time it takes for delivery. m(_ _)m
