Get the most out of each bar of soap. We all know what happens when soap is left to sit in water. A slimy mess. Soap is made to dissolve in water and when left to sit in water, it dissolves and leaves an unwanted mess and reduces the life of your bar of soap. Soap dishes allow the soap to be raised out of water as it drains. Your bar will last longer, which means you'll get more uses out of each one. At 5 in long x 4 in wide, the soap dishes are small, compact and will fit our bars of soap.
