For small businesses that write their own checks, this EGP blank laser check stock is a professional and secure solution. This is a bulk pack of 2500 high-quality checks (that's a lot!), perfect for businesses that use a single checking account for both accounts payable and payroll. Each sheet is standard 8.5 x 11 inch, 24-pound paper, and is formatted as a 3 2/3 inch bottom check with two vouchers attached (perforated at 3 2/3 and 7 1/3 inches). You print them yourself using your accounting software, a laser printer, and special MICR toner for the bank routing numbers. These checks are packed with security features to prevent fraud: gradient copy-void pantographs, micro-printing, chemical reactive ink, fluorescent fibers, a padlock icon, and more. They come shrink-wrapped in packs of 500. Please note: these are BLANK checks – they do not include your business info or a signature line; you print all that. This is a cost-effective way for businesses to produce professional, secure checks in-house.
