From the manufacturer - Don’t let your soap turn into muck! Soap Lift® is made of a multi-directional bioplastic that allows water to drain and air to circulate. They can be used in soap dishes, on shower shelves, or on countertops. Cleans remarkably well by simply holding it under running water and giving it a few squeezes.
Approx. size: 2.75″ x 4.25″. Can be trimmed to fit soap dishes, if necessary.
