The Kamui Scaled Diamond Set is a stick-on set that is a billiard training and aiming aid for players who use the “Diamond” system or just need a little help improving their wall strokes. It is very easy to install and does not require special tools. Simply peel off the backing of the sticker and connect the individual diamonds around the table. Cut off the excess sticker where the sticker extends beyond the pocket. Kamui Diamond Slicer stickers are not designed to be moved, so be careful when applying them!
