Material: Fiberglass Height: Approximately 94mm Base: Approximately 89mm Deep fin box height The included soft case is slightly deteriorated. ◎There are two types of Future Fin box heights: the deep type with an "f" mark on the box and the shallow type with an "x" mark. We cannot accept returns, exchanges, or claims due to incorrect fin box height. Please check your board before purchasing. Thank you for your understanding. If the fins are difficult to attach or detach, please adjust them by sanding, etc. #Longboard #Midlength #Shortboard #Funboard #Simmons
