Sakura® Souffl?© 3-D Opaque Pen Sets are incredible gel ink pens that dry with a 3-dimensional finish. These unique and amazing pens are different in that the end result can be seen on dark surfaces as well as light backgrounds. Souffl?©s work on paper and cards, but for best results use on non-porous surfaces such as plastics, coated papers, acetate, vellums and glass. The delicate, fluffy line requires only a few minutes to dry, but the results are eye-catching and fun. With Souffl?©, every line you write will make a tactile impression. Write slowly to let ample ink flow and let dry completely. They are great for gift tags, holiday tree ornaments, hand-made stationery, altered books and rubber stamping. 10 pc
