I purchased this item used several years ago. I detached some parts from the runners to try a test assembly, but I broke a wheel in the process and repaired it with glue, leaving it unfinished. I've listed it as junk, so I've set the overall condition as poor, but I think everything except the wheel is usable. This is an old product, so I cannot accept any claims or returns after purchase. I believe it's unlikely to be available at a lower price in the future, so please refrain from asking for a discount.
