I had created this for myself back in the day to keep track of missed shots and drills, before cell phones were good enough to watch videos on while you played or practiced at the pool hall. Just found these, forgot I had them, there's 14. They worked a treat, fantastic little practice tool. Make an offer on em if you're interested. They cost me 4 dollars a piece to make. Not worth selling individually, but if you have students these are great. I had made a large batch for someone who coached, he was very happy with them. They're slightly larger than a pack of cigarettes. Easy carry and light weight.
