Sold by weight. Look at 2nd picture for reference of what 1g and 2g looks like. 1g pot means 1g of shell fragments are placed in a 5ml sized pot. 1g of shells will not fill the pot completely, so do not expect a full pot.Shells are fragile and can easily be broken down into smaller bits for nail art, resin crafts, and other crafts.// PACKAGING- glitters: ziplock baggies unless 5ml pot is chosen- nail slices & metal decorations: ziplock baggies- other embellishments: ziplock baggies unless 5ml pot is chosen- pigment powders: ziplock baggies unless 5ml pot is chosen// IMPORTANT NOTESI try to take as accurate pictures of the colors of the glitter and all other items as I can. However, please note that under different lighting and on different computer screens, there might be some variation in color.
