These are a pair of our current design that just didn't come out perfect. The red leather is a bit close on one end of one cuff and the stitching is a bit wonky on the back with this pair. Pictures are of actual product. Video is from the current design. 7" long. There is only one pair of these available. Price is $25 for the pair. 
 
2" wide strip of leather with leather strips leaving a 1/2" channel in the center to hold your hand cuffs in place while providing some padding against the skin. Hand cuffs not included. 

IMPORTANT!: Measure wrist circumference 2" up arm from where cuffs would normal rest. That is the size you want.
