As the title says, you all know what they are. I have x3 of these going spare, all black, all used but in very +good condition. I can provide a photo/photos if required though. I'm just not using these much anymore and even if I do use them I prefer the 3'' ones that now offer a little more support to my back.
Let's say £15 each posted or I could do all 3 for £35 for my UK compadres.
All prices obviously in GBP, payment by PPG is king.
Your straps. Sell them to me.
