Your dryer will dry much faster if you put the dryer balls in the drum with the damp laundry. Why?Because these two balls move the wax extra with their knobs.In addition, your laundry will be softer and you will suffer less from creases.The dryer balls use specially designed knobs for to remove the stiffness caused by water drying in the fabrics and soften the laundry without using toxic chemicals.The two balls have different elasticity (one is harder than the other) and different shaped softening nodules.< br />The square bubbles compress the fabric and make the fabric softer and the round bubbles relax the fabric and reduce its hardness. Together, they ensure that the laundry is refreshed and separated during the drying process.They also absorb the heat and transfer it to the clothes during the laundry drying process, making drying easier.
