As an alternative to single use dryer sheets, wool dryer balls helps to create space between the clothes in your dryer to allow better airflow and faster drying (while also helping to reduce static). Use between 4-8 balls depending on load size. Comes in sets of 8 but with no additional packaging so you can sell as individual items and buy in bulk. You can also separately purchase cotton produce bags if you want to pre-pack these (e.g., sell 4 wool dryer balls as a bundle in the "cotton solid produce bag" that we offer). Like many of our products, this item arrives with no individual pre-packaging (besides the plain box) to reduce material waste for a more sustainable supply chain. We use paper and cardboard packaging and dunnage to ensure it is shipped safely. Not using plastic packaging and minimal usage of other biodegradable / recyclable packaging is a key part of our mission as a brand of sustainable personal care and home products.
