[Product] Kumano Fin System Alex Knost ★ Kumano Fin System Alex Knost 9.75 Size: 9.75" (Height: approx. 25.5cm, Base Width: approx. 14cm. Please allow for some margin of error.) [Condition] This is a beautiful item, used 2-3 times after being purchased new. I bought it for a mid-length board, but I sold the board, so I haven't had a chance to use it and have been storing it. The color is "VOLAN," with a beautiful cross pattern. Fin bolts are not included. There are areas on the side of the fin that look like white scratches, but they were there from the time of purchase and are not scratches. Recommended for mid-length and longboards. ●What is the KUMANO FIN SYSTEM? It is an innovative one-touch fin system devised in Japan. ●The biggest feature of this fin is its thickness! ●Normally, it is common for longboard fins to use 40 layers of fiberglass, but this fin uses 60 layers. ●Although it has a slender template, it seems that they have made it thick overall and not flexible, with only a little flex at the tip. ●Fins from the 50s and 60s were all quite thick, so it seems they were conscious of that.
