Specification: Diameter: 72MM Height: 65MM Laundry Balls with Stain Remover Our Laundry Balls save you money, instead of buying countless bottles of detergent and wasting time measuring them. Each ball can be re-used for multiple washes, and all you need to do is just drop one in with your washing! The detergent balls inside the main ball wear down over time as they release non-toxic cleaning chemicals. Around the ball, a protective foam ring keeps your clothes safe as the balls inside spin. The stain removers are effective at removing tough stains, including ink or wine.
