Keep it simple with these industry standard economy rubber hex dumbbells. They are made out of the very durable industry standard material: ASTM A48 Class 20 grey iron joined together by a solid 1018 cold rolled steel chromed handle for exceptional durability and longevity. These "eco bells" may not have the super tight weight tolerance of the PR Lifting rubber hex dumbbells.. but then again, most don't.
The eco rubber hex dumbbells will have more of a rubber smell compared to our regular PR Lifting bells and may have some slickness left from the manufacturing process.
