I am trying to send my snowboard back to the States. Japan Post said they could do it, but they brought the board back to my apartment (after I had filled out the form and paid for it) because they only accept packages 150cm in length. My board is 157 cm. If there is no affordable way to ship it back, does anyone know of a place where they buy used boards? It is a 2008 Burton Twin with the skull graphic on the front, I just bought it brand new last year. Thanks!!
