Thank you for viewing. This is a metal ball chain S (total length 72cm) for a bathtub rubber stopper, perfect for the bath. This is a replacement chain connected to the bathtub rubber stopper. Although it is new and unused, one of the retaining ring's circular rings is missing because it was used for repair. The only difference is that the chain length increases as it becomes M or L. The ball diameter is about 5mm, which is the largest diameter sold, and I think the ball diameter is L, not S. Please consider size S only for the chain length. The balls are large, so they didn't fit my bathtub. Brand: LIFELEX Purpose: For bath Type: Ball chain Length: Chain, total length 72cm Material: Metal (probably stainless steel) Retail price: 547 yen (tax included) Other: With a circular ring (Originally, there were two. However, one was removed for reuse, so it is not included)
