Use these sponges as a natural alternative to plastic and synthetic sponges. You get a set of 2 sponges called Reseda, which are made of 100% wood pulp. They don't scratch the surfaces, but clean them gently. It's best to combine the sponges with Meraki's dishwashing liquid. Although the sponges are everyday items, their neutral color creates exactly the calming and natural mood that Meraki stands for.
