Solid Tamper-Proof Key Rings are made of incredibly strong 4mm solid stainless steel with a break strength that guarantees the safety of your keys once they're secured on the rings. 

The smooth patented steel allows your keys to move freely around the entire ring without any obstructions to interrupt their movement. 
  

Tamper-Proof Key Rings come in five sizes, from a one inch ring to a four inch ring.
