This Mica is a nontoxic waterproof mineral that adds a beautiful and vintage look to your crafting and decorating. Much lighter than glass glitter. The same mica was used in the 1800s on German ornaments. Why not bring back the nostalgia of yesteryears? This is not a reproduction. Available in 1 lb bags. This is the same mica we use on our reproduction ornaments. This is not a man-made material. Our mica flakes are non-toxic and safe for use in a plethora of DIY projects not limited to art, craft, and decorative projects. Please email me with questions.
