This listing is for a QTY of 500 randomly selected KF25 clamps. They are either brand new or used and in pristine condition. 40% kurt lesker list price. check my other listings for other KF clamp sizes. PLEASE NOTE - I am happy to combine shipping, however, as an example, only 10 pieces of KF50 clamps will fit in a USPS bubble mailer. Where as more would fit if you purchase a smaller size. I will charge actual cost for whatever shipping means end up being used for combined orders.
