Dark gold SF. Superfine (SF) – The first, and by far our most popular due to the ease of applying, is our SF. The grain size of this glitter is our smallest, ranging in size from a .004 x .004 to a .006 x .006. This size of glitter does not offer as much sparkle, so tends to be less dramatic, but is still brilliant and stunning to wear. It is a great cut for a day or â€˜officeâ€TM look and works beautifully as an all over eye shadow and lip shimmer.
