The listing is for 750lbs of new solid Rugged Fitness bumper plates in these exact increments:
20 45's = 450lbs
12 25's = 300lbs
(You cannot mix & match your own weights to total 750lbs. For example, you cannot get 75 10lb plates to total 750lbs for $750. You must get the increments and quantities listed above.)
Bumper plates are brand new in box and are great quality!
