The cartridge is very easy to refill. It takes less then 5 minutes to complete the job, even if it's your first time. You don't need to buy expensive tools or kits. These toners are Brand New in a factory sealed bottle and warranted to be free from defect.

I ship the toner with detailed instructions and a screw-on funnel with each shipment. We DO Recommend the REFILL TOOL with this refill kit.
