Kids love glitter, so this is a cool product to add some extra sparkle to projects or arts and crafts. The tubes are shaped like a marker and have a small tip for precision. The kids like how it makes their things look more fancy. We have used them a lot and they work great. I like having things like this for the kids to sit down and do so we keep lots of arts and crafts supplies for them including these glitter glue pens. They are a little expensive but they love them so we keep buying them!
