If you leave a comment, I will remove the listing from silent transaction, and I will create a dedicated listing for 1589 yen. This is to avoid being a victim of silent transaction users, which has happened many times before. This is a set of red and black rubber stoppers of various sizes, including used ones. Some were used to stop water in hoses and pipes (some are new). The size is indicated on the head of the rubber stopper, but because the purchase dates are far apart and the manufacturers are not the same, there may be slight differences even with the same size. (27 total) There are various types of rubber, such as SBR, NBR, butyl rubber, silicone rubber, fluororubber, and natural rubber, but it is unknown. Judging from the situation, it is not likely to be butyl rubber, silicone rubber, or fluororubber. Some are old and slightly dirty. 34 1899 26 2099 19 2109
