Environmentally friendly and reusable: as sustainable alternative to tennis balls in the washing machine and conventional balls for dryers, our balls are made from 100% New Zealand sheep's wool and replace disposable dryer sheets. Energy Efficiency & Cost Savings Our dryer balls for tumble dryer speed up the drying process by 20-40%, which not only saves energy, but also noticeably reduces your electricity bill. Naše sušičkové kuličky činí vaše oděvy super měkkými, bez záhybů a mazavých. Ideal for down jackets and pillows: our dryer balls are specially designed as dryer balls for down jackets to increase drying efficiency and are also perfect wash balls for down jackets that protect the material. Hypoalergenní: sušicí koule snižují lepivost oděvů způsobenou statickým nábojem. Naše koule do sušičky jsou bezpečné pro nejcitlivější pokožku, což je činí ideálními sušicími koulemi pro rodiny s dětmi a alergiky. Praktická velikost a skladování: průměr koule 7 cm. The XL ball provides the best performance for shortened drying times.
