In our Quality Assurance process we weed a lot of parts. These pieces might have a slight miss-cut, or have less than great wood-quality. Every piece we put in a B+ Board is “playable”, but might not fit just perfect. It’s a shame to throw away all these almost OK parts. We figured that some people might want a lower risk investment if they were going to unleash a bunch of wild children in a painting extravaganza. You might also just want to have a really big board for a weekend tournament. Do what ever you want with these. Spray paint them all in 2 seconds. Assemble a mega board! Bejewel them with your 3 year old niece.
