I am selling 30 L-size Tai Rubber (Tairaba) caps. These are equivalent to the L size of Jackall's Bin-Bin Backfire Caps. They feel slightly smaller than Jackall's. The size is based on my personal experience using them, so it's subjective. Please check the size in the second image before purchasing. There may be manufacturing burrs, so please remove them before use. Price negotiations are not accepted.
