24 Karat glitter. Glitter size is (.200) or 6mm. HUGE gold holographic glitters. You will get a 12 Gram Bag by weight, not a jar. Great for arts & crafts, resin, diy projects, snowglobe tumbler cups, diy projects, card making, jewelry making, slime, shaker charms, badge reels and nails (works best on really long nails because the glitters are really huge) See how big a 12 gram bag is at this link: click here
