Felted Wool dryer balls that take the place of your dryer sheets or fabric softener. Throw them in the dryer with your freshly washed clothes and they will reduce wrinkles, soften clothes, and decrease drying time! They are fabulous! You can add a drop or two of essential oil for a fresh scent! This set includes 6 dryer balls and a sample of Young Living Essential Oil. They do not help with static electricity, but a 1/4 cup of vinegar added to the washer in place of liquid fabric softener will do the trick. Colors may vary. This set is gray and natural – set of 6. Smoke-free/Pet-free environment, handcrafted by me!
