This sticker is made from another material Kentaro tracked down for us. It's a thin black rubber with a slight texture to it. These are being sold in our standard sizes for large and small bearings. This is the same material that Buzzon is using, but these are manufactured with our own equipment. These are not the same sizes as are being sold standard by Buzz-on and are good on many different yo-yos.
This sticker is available in all sizes.
