Please note: Our bumper plates are shipped with a protective layer of an oily substance, plastic wrapping and a cardboard box to preserve the quality of the bumper when stored and shipped. So they may have a strong rubber smell initially. The rubber smell will dissipate over time, especially when used. In a well aired gym this is just a matter of days. To speed up the process please wipe the bumpers with a soapy solution and store them in an area with good ventilation.
