SCUBAPRO TWIN SPEED Fins, Size S-M Black/Gray Made in Italy. - Brand: SCUBAPRO - Model Name: TWIN SPEED - Size: S-M - Color: Black/Gray - Country of Manufacture: Italy Thank you for viewing. Used for skin diving with 25cm marine shoes. After use, it was washed with fresh water and stored in a dark place. Since it has been used infrequently, I think it can still be used. Please check the condition and feel of the product in the images. Please purchase if you understand the condition as it is a used item. *I am also selling other diving equipment. If you purchase multiple items, I will combine shipping and offer a small discount if possible. SCUBAPRO and Mares products can be combined for purchase. Please feel free to contact me via comments.
