We take our super pure, tested free of chemicals, wool and we super process it organically to remove vegetation, dust, and excess oils. The result is a lofty, clean wool that does not have the pungent odor of many natural wools. A unique wool pillow with woollie balls that prevent compression and can be occasionally machine washed on delicate. The wool balls give a feel more like poly filled pillows. Ours are then covered with our organic cotton European jacquard for a fancy look .
