Mobius Knee Braces size Medium

I have a set of Mobius knee braces that have about 5-8hrs on them. Bought them new in 2017 and ended up watching a few to many Ryno videos and decided to start riding without braces and have not looked back since. Braces are in good shape. One side the ratchet wheel sticks on occasion but still works as it should. I contacted Mobius about it and they said it probably had dirt in it and to send it in for a tune up but I stopped using them shortly after that. Looking to get $400 shipped Contact Matt @ 918-575-8044 for pics
