Each board size may vary slightly.
Until around 2008 or 2009, the standard size fingerboard was between 26-28mm wide. It is only recently that the standard board size has grown. This is for all the people who want to go back to that old board feel, it's a lot of fun. Flip tricks are faster and tech tricks are easier.
Note: You are paying for one (1) deck.
