SAKURA-Souffle Opaque Ink Pens. Assorted 10-pack (1 each) in popular pastel ink colors: yellow, blue, green, orange, purple, light green, light orange, pink, gray and white. This incredible gel ink pen has a 1.0mm ball diameter for bold .7mm line effect, then dries to a 3-dimensional opaque, matte, pastel color line! (Embossed effect is delicate and can be crushed-down, so careful handling is necessary, just like a real baked souffle!) Great for gift tags, holiday tree ornaments, hand-made stationery, rubber stamping flourishes and cell phone decorations, however, for best results, use on non-porous surfaces such as plastics, coated papers, acetate, vellums, and glass. Eye-catching and fun, ideal on dark surfaces as well as light backgrounds.
