Jack And Jill is part of the "Mother Goose Nursery Rhymes" Glitter collection. This come in a 12 gram bag by weight, not a jar. These are micro diamond crystal glitters. Great for arts and crafts, resin, diy projects, slime, shaker charms, snowglobe tumbler cups, etc. These can be used for nails but they are like very thick crystal pieces and would be very 3d and would stick up off the nail kind of like sugar crystals. See what a 12 gram bag looks like: click here
