These cellulose pop-up sponges replace foam and plastic sponges for dishwashing & cleaning but with the same function that most are used to. They magically expand in size with water to work like a dish sponge, but without the plastic waste! Cellulose is made from wood pulp and 100% compostable. Now with a cotton loop for hanging. Comes in a 3-pack. Care Instructions: Rinse, squeeze, + place in a dry spot to allow water to drain in between uses. Submerge in boiling water for 5 minutes to disinfect or pop in the dishwasher.
