This is a silicone skirt for the GULL COCO mask. It's used and old. 1200 yen each. If you only want one, please contact me via the comments. I plan to ship it via Letter Pack Plus because it may deform if packed small, but if it's okay to pack it in a way that squashes it, I'll lower the price, so please let me know if you'd like that. (An elderly relative closed their diving shop, so I'm clearing out the warehouse stock.) *Shipping from Okinawa often takes about a week to arrive. Please refrain from purchasing if you are in a hurry. *I have a cat. I will clean it thoroughly before shipping, but please refrain from purchasing if you are concerned. I do not smoke. *I will use recycled materials for packaging.
