This listing is for one (1) 15ml bottle. The brush on these bottles is slightly curved almost like a spoon which helps for chunky glitters and the extra wide mouth makes getting the glitter out easy. To get a nice smooth coat, completely wipe the outside of curve clean and dab the polish on to the nail. Since the glitters are chunky its easier to dab the polish than to swipe. Seal with a top coat to secure edges on larger glitters.
