Pair of balls for dryer Blue / Green The dryer balls use specially designed knots to physically break down the stiffness created by water drying in the fabric, thus softening the laundry without introducing toxic chemicals.The two balls have different breaking loads (one is harder than the other) with softening nodes of different shapes.The square knots compress and soften the fabric;the round knots relax the fibers to reduce hardness.They work in combination to lift and separate the laundry during drying.They also retain heat and transfer it to clothes during drying, favoring the drying process.    Supplier Code: 9029791861 EAN code: 7321422255810
