Since the metal tag is missing, I'm selling this for less than half the original price. I seem to have removed the metal tag when I tried it on once, and then lost it. After that, I thought I might use the collar someday, but I ended up not using it and kept it at home. The crossed thread part is sewn quite roughly, but that gives it a handmade feel. - Reference Weight: Approximately 5-14 kg - Neck Size: Approximately 26.5-34 cm - Thickness: Approximately 1.6 cm - Hole Pitch: 8 holes, approximately 1.5 cm apart - Weight: Approximately 50 g It's still usable, so perfect for dogs who need a collar!
