I have had a Ryobi biscuit joiner for many years and don't use it a lot but now have used almost all the biscuits on hand. They seem to be an odd size and I can't seem to find any locally or on line. The can they came in says "R3" biscuits. They measure 1" X 1/2" X .100". I have no idea where they came from or even if they came with the biscuit joiner when I bought it. Anyone have a source? Thanks, Jim.
