These are very used but working. Please see photos for exactly what you get you will get what is shown in the photos exactly so refer to those for condition. The rubber part that goes around the wheel looks replaceable and is a wear item you should be able to get from the manufacturer and just replace if you wanted-- or you could use some type of filler to fill in some of them. They were taken out of use simply by a company because of time used.
Sold AS IS as parts As shown fast SHIPPING from central CA near SF hub so it gets on its way to you fast. Bonus of dealing with a real person not some huge corporation.
5 used pieces a little grimy but enough rubber on them to be good for awhile
