Chain Martingale Option
This option replaces the nylon web martingale with one made from chain (Available in chrome only)
The Chain Martingale Option can be applied to Keeper Style flat martingale and Loop Martingale style collars, both with and without a snap buckle and in 3/4 inch, 1 inch and 1 1/2 inch widths.
Adding this to a Vegas style martingale collar will effectively make it a Loop Martingale collar.
This option is NOT available on Keeper Hidden Prong collars.
Addition of an upgrade to a collar will make that collar into a Custom Collar and the collar will become non-returnable for any reason other than workmanship.
