QUIKSILVER Amphibians board shorts size 40

Quiksilver Amphibians board shorts. I'm not positive of the size but I believe they're size 40. they have a single button and zipper closure. two front pockets and one buttoned back pocket with a keyring attached to the pocket. they have some stretch. the waist measures 20 and 1/2 in, the rise measures 14 in, and the inseam measures 8 in. I have two pairs of these so bundle and save.
