Thank you for viewing. I purchased this, but I'm not sure if I'll have the opportunity to use it in the future, so I'm putting it up for sale. It's for the ankle and can be used for surfboards and SUPs. Although it's unused, please consider it as having been in someone's possession, and we appreciate your understanding.
