look at the the photo with your left eye closed as the ones on the left have been sold.
ones on the right are still up for grabs - get down to Halfords and you will see the Fibrax pads alone - which i think is what these are - will set you back a fiver, but for the same amount oif cash tokens, you get them fitted to a holder plus a spare matching holder delivered to your front door. Go on, you know you need a spare set.
