The cartridge is very easy to refill. It takes less then 3 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.

Each Kit Contains 1-150 grams of toner, which is one full refill.

I ship the toner with detailed instructions and a screw-on funnel with each shipment.
