I was looking for "deep dish" style olympic weight plates (2 inch hole diameter). These are sold as single plates so you need to order two to get a pair. They are smooth on the back and around the top. The center hole is also smooth. They did NOT arrive in perfect condition, but I accepted that they would slightly imperfect for iron plates (the shipping box is basic and they are not overly protected; there were slight scuffs and paint imperfections). What I like most about these plate is how easy they are to carry and load. The edge/lip is wider (deep dish) and that makes carrying them easier than regular weight plates. They are also fairly accurate for the described weight. Overall I am very pleased with them.
