These martingale collars are finished with a fabric finish including materials such as 100% cottons, cotton blends and soft flannels. All are strengthened with interfacing.
The Fat Paws team source high quality fabrics and all are prewashed and laundered to check for colour fastness and durability.
Cotton fabrics will fade a little with time and with everyday wear, but are easy to maintain and all can be machine washed unless stated otherwise.
