These laundry cubes shine with more planet friendly ingredients and highly concentrated cleaning performance. Unlike laundry pods and strips, these cubes dissolve in hot or cold water, are PVA-free, and deliver powerful cleaning that takes on stains and odors naturally. Each cube measures 7/8 inch (22.22 mm) and is designed to go directly into the drum—not the dispenser—for the best clean. Tin comes with 64 cubes/loads How To Use: Use only one Laundry Cube for each regular sized load. Throw directly into the drum before adding clothing. Wash according to instructions on garments. Always test on garments that may bleed or fade. Nellie's Laundry cubes are safe for HE and standard washing machines and dissolve in hot or cold water. Once you're done with your tin, let's refill it! Biene will be offering laundry cube refills soon.
