Stainless Steel is the hardest and most durable of any of the metals used for collars.
This stainless material is 100% rust proof and the links of this collar are supervision welded.
If you have a dog that has any type of allergic reaction to metals then you need a stainless collar

At last you can enjoy a prong/pinch collar with a handle. This is a first for a collar like this. Its use is without saying.  A great tool for a release training collar.
