I need two scuba fin spring straps made from stainless steel (usually 316 stainless, which is the type of stainless steel and is best for marine environments). Mounting style (to each fin) is as shown but aesthetics with pull tab, casing around the spring, etc., can slightly vary; however, no plastic buckles or open pins that one needs to bend, please. Pull tab, loop, or whatever can be different. New, or gently used in like new or very good condition, please. Photos of desired style of fin straps are shown; these are representative examples of what will work but are not exclusive examples. I am not sure what length I need, but I wear a large fin and size 10 soft neoprene bootie with soft sole. I found the first two photos on Aquatec's website. Aquatec has not updated its website since 2019 and it is unclear if it is still operating in Taiwan.
When you write, please let me know what city the fin straps are in and what days and times are available for pickup. Please also send clear, sharp photos. I desire to pick up as soon as possible.
