Urethane Foam 3-Layer Sponge (3 Pack)

A sponge made with non-woven fabric and 2 different urethane foaming layers. Each layer produces different size foam. Large bubbles maintain cleanliness due to good drainage, and fine bubbles maintain good foaming and ease of washing. The shape is perfect for getting into the corners of lunch boxes and narrow glasses.

Built with a three-layer structure, each with a different function:

Upper Layer - Nylon non-woven fabric captures dirt firmly.
Middle Layer - High-density urethane part creates fine foam.
Lower Layer - Urethane part with large air bubbles to keep clean and drain well.

The white color makes it easy to see when it's time to replace the sponge.

Also available in a gray color, that makes color transfer after cleaning less likely.
