Thank you for viewing. This is a fin for a longboard from ALMOND surfboard. It was purchased new and has been stored without being used even once. It was stored in a case, so there are marks from the case on the back. Please check the photos. As a bonus, a case and a repair kit are also included. Size: Height: 25.5 cm Base width: 15.5 cm Please allow for some error due to amateur measurements.
