These liners are designed to fit the Pedicure Tub (C1531). They are disposable and should be replaced after every use. Their sole purpose is to prevent the spread of infectious material (bacteria, fungus, and infectious diseases) from one person to another during the soaking process. They are durable and lightweight. Because the liners are disposable, the tub doesn’t require scrubbing or cleaning between every use. The liners are made out of recyclable plastic. 100 per pack.
