This is a set of a leash and collar for small to medium-sized dogs from Segawa. I purchased the set, but I hardly used the collar. I used the leash for a few months until it became somewhat worn, and then I stored it at home. The German snap hook is a valuable item made by the German company SPRENGER, which is also used by a certain brand. I believe it can still be used for a long time.
