About The Whoopsies
Less than perfect, but still entirely useful.
FREE prototypes, B stock, and functional defects. At worst the products listed here will be slightly impacted by a design defect, but still entirely useful. At best they'll just be left over stock of an older product which has been replaced by a newer version.
Help me keep these subpar-but-still-totally-useful boards from a life collecting dust on my shelves.
Check back often and add a bunch to your order if you see anything that interests you. No purchase (of other items) necessary. You'll just pay the shipping.
