California Proposition 65: This product contains a chemical known to the State of California to cause cancer. Toilet bowl mats are constructed with a heavy, high-friction plastic that grips to clean, dry floors to reduce slipping and tripping. The hexagon designed grid effectively directs liquids quickly into the absorbent core. The flexible construction allows the mat to easily conform to uneven floor surfaces, and makes the soiled mat simple to fold or roll up to fit in the receptacle for effortless disposal. For use with all standard toilets.
