These Stones will remove pilling, lint and fuzz from your sweaters, sweats, flannel pj’s and other similar fabrics. I hand cut these in our shop, from a volcanic hardened ash substance. These stones make great gifts, and last a very long time. No batteries or electricity needed. Totally easy to use. Each stone is wrapped like you see in our photos, and each will have a little ‘How to use’ instruction sheet tucked just under the label. Questions are welcome. Thanks For Stopping!
