Metallic shreds glitter, small size glitter these have been cut up into small pieces, they are not long strands used for filler, if you need finer glitter they can easily cut with scissors to make smaller pieces for the size you need for your project or nail art, jewelry making, fairy dust flakes, etc. Commonly used to make party favors, keepsakes, thank you gifts, wedding party favor gifts, anything you want to add some sparkle and shine, the light hits it and it just lights up with color, look at the pictures and you can see when the light hits it the colors are beautiful, just a little bit goes a long way, works great in the resin I use, would be great for jewelry, scrap booking,mixed media arts & crafts,, adding to molds for the diy, the glitter didn't bleed on any of my projects and it mixed well with the colors that I used. Packed by volume not by weight. This glitter flakes come in a 4x4 bag stuffed full couldn't fit any more into the bags, them taped up because it has so much in it, the glitter was falling out I stuffed to much into the bags. I randomly weighed a couple of the bags and they weighed approximately 1 ounce in the bag and counted out how many Tablespoons were in one of the bags, that random bag had 20 rounded Tablespoons of this beautiful iridescent opal glitter, I just love this stuff.
