Uni-ball Signo Pens Specially formulated ink helps prevent check fraud.
Check washing is a form of check fraud. Check washing is a process where a thief erases the ink from a stolen check using common household products. Many uni-ball pens, such as the uni-ball 207 use specially formulated inks that contain color pigments that are absorbed into the check's paper fibers, trapping it from check washing efforts. Non toxic. Made in Japan.
