The TOILET BOWL RIM HANGER WITH NON-PARA BLOCK fits most toilets and deodorizes up to 1,500 flushes (30 days normal operation). The compound inside gradually dissolves, coloring the standing bowl water a fresh aqua as it imparts a nice fragrance. Replace when the water is no longer colored. Blocks are acid-free, water-soluble and 100% biodegradable.
