The Souffle ink pen creates an embossed effect on most any surface in minutes, without messy powders and heat guns. The ink dries to an opaque, matte finish, which works well on both light and dark colored surfaces. Embellish gift cards, scrapbook pages, ornaments, and so much more. Bold 0.7 mm lines provide a variety of possibilities. Souffle ink is waterbased and odorless. It works best on non-porous surfaces such as stickers, plastic, and glass.
