Pumice Cleaning Stones for porcelain cleaning in kitchen/bath/pool/etc MOMENTUM

We have very hard water which leaves residue in our porcelain throughout the house (sinks, toilet bowls, tubs, etc). Consequently, our drinking water is bottled. However, every day we use hard water for tasks including bathing, flushing, washing dishes, etc. Pumice removes calcium and lime buildup as well as hard water stains without scratching because of it's fine abrasive grit.

This is for a set of 4 pumice stones with attached handles. Wet the surface, wet the stone, use gentle abrasive action to remove buildup.

UPDATE: When unwrapping one for use, I looked at packing cardboard, which clearly stated price of $1.49 each.  This would be about $6 for a set of four. I paid $10.49, or about $4.50 over retail. They work fine, just feel a little disappointed about the company itself.
