Each cloth is a unique mix of 70% Cellulose wood pulp and 30% Cotton. Not only are they naturally anti-bacterial, but they're also incredibly versatile: use them to clean dishes, countertops, furniture, and even plants! Plus, they can hold up to 15x their weight in water, making them the ultimate cleaning helper. And when they're ready for a wash, just toss them in the machine or top rack of your dishwasher. With average use, they'll last 2-3 months, but can be used for up to 6-12 months or 200 wash cycles. Just remember to avoid tumble drying and fabric softener to prevent shrinkage. Designed in the USA. Measurements: 6.75" x 8" (17 cm x 20 cm). 100% compostable and biodegradable.
