CA Prop 65

This product contains recycled and reclaimed rubber
materials. Recycled and reclaimed rubbers are made
from the by-products of used tire crumb. The exact
origins and compounds of each tire is unknown, and
it is not feasible to test every tire that is recycled.
Due to this fact, Rubber-Cal has chosen to provide a
warning that this product may expose a person to one
or more chemical ingredients listed in Proposition 65
as harmful to human health.
