Pentel's Dual Metallic gel roller pens are something a bit different. Each pen gives you not one, but two different shades, and it doesn't involve flipping between twin tips. Shimmering metallic ink ensures that - depending on whether you're writing on black, white or coloured paper, and the angle at which you hold it - two different shades will be apparent. Pigment/dye hybrid ink is acid-free and scrapbook-safe. Hybrid ink and a 1mm tip, which makes for super-smooth writing. Perfect for cards, gift-tags and when you want to make a piece of artwork really stand out.
