Diving Equipment This is a strap to secure your octopus so it doesn't dangle. It fastens with Velcro, but will come off if you pull the octopus strongly underwater. Unused and in good condition, but the case is dirty, so only the contents will be delivered. Please understand. ☆Shipped via Yu-packet Post or Yu-packet Post Mini. I ship immediately, but it seems to take 4-5 days for delivery. Please be aware of this if you are in a hurry. Thank you for viewing.
