We test many toner samples from toner manufacturers. Most are rejected as they do not meet the look and specifications of the OEM toner. The toner we sell DOES match OEM toner! You will save up to 80% on the cost of your toner cartridges. You will save even more money with our multi-bottle kits available in our Amazon store. Refilling your own toner cartridges is more environmentally friendly than buying new, compatible, or even remanufactured toner cartridges. We provide easy-to-follow instructions with photographs of the process. The process is so easy that most people do not need help. But if you do need help, we're just a phone call away! We guarantee that you will be happy with your purchase or we'll refund your money.
