All clamps work fine.
Three clamps show wear around the inside of the clamp (they are on the top row of the photo). They do still do the job just fine. $20 each.
Three clamps have seen less use and show only a small amount of wear around the inside of the clamp. $23 each.
I will ship these clamps free within the US via USPS Priority Mail if you buy all six clamps at once.
Otherwise, I will send these via USPS First Class Mail at buyer's expense (likely about $3.55 per package).
