We are listing 30 Tai-Raba (鯛ラバ) caps in size L. These are equivalent to Jackall's Bin-Bin Backfire Cap, size L. They feel slightly smaller than Jackall's. The size is based on personal subjective experience from actual use. When considering a purchase, please check the size in the second image before buying. There may be manufacturing burrs, etc., so please remove them before use.
