I think you will be pleased with what you receive. I know others have mentioned places to buy cheap blades, but we KNOW the name OLFA means quality. They were in new, sealed packages and regardless of what someone else said, I do not think they are sharpened and repackaged. I firmly believe this man is being honest and gives us a good buy.
I put my used blades in one of the plastic holders, then put it in a small mailer. It cost 87 cents postage to mail. No return postage required.
