Do not be a victim! Check washing is a form of check fraud where criminals steal checks from the mail and erase the handwritten ink using common household chemicals. They then rewrite the checks to themselves for any amount they choose. The pigmented ink in the 207 Gel permanently binds itself to the paper fibers in the check, and cannot be washed off or removed! The new and improved uni-glide gel ink formulation offers a clean write every time. With improved fade and water resistant 0.7mm blue, black, purple, red and orange inks, you can't afford to write without this pen. The stylish design and comfortable grip of the 207 Gel will top off a promotional plan for any business. Ink color matches trim color. Refillable, 0.7mm tungsten carbide ball delivers a 0.4mm line width. Waterproof, pigment ink. uni-ball 207 Gel can be customized with a multi-color imprint for an additional 8-cents per pen per additional color. Price shown is for one color imprint. $40 imprint set-up.
