Smart Sheep
Genuinely plastic-free by design: the dryer balls are 100% felted wool with no synthetic core or filler, so there's no plastic substrate to shed or discard. It's a single-product focus, and that product happens to be one of the cleanest swaps in the laundry room.
How clear are their specs?
States plainly that the balls are 100% New Zealand wool, felted all the way through, and undyed/unbleached - no vague "natural fibers" hedging.
