  Important Note: As part of the refill process, you will need to make holes in each toner cartridge. Although you can use a utility knife, it is much easier to use one of our hole-making tools. It is the cleanest, easiest way to complete the refill process.To purchase a hole-making tool, copy and paste the following link into a browser --> http://www.amazon.com/gp/product/B00O7JRWE2
