Carioca 3D Raised Effect Glue Pens (Set of 6 Glitter Colors) Convenient 3D glue pens can be applied directly from the tube like a pen and are extremely easy to use. The 3D glue pens create a raised design once they are dry. Just let the paint dry for five hours and set it with a hair dryer or for fabrics, use an iron on low heat on the backside of the garment. This vibrant 3D glue features six glitter colors and can be used on multiple surfaces. Kids love the bright, bold colors of this art set.
