I bought this refill and there are instructions online on how to use it. The only thing that didn't come with the baby I needed was a piece of duct tape. It's absolutely wonderful and saves a ton of money. Ink quality is good. My color ink cartridges weren't completely empty so I didn't invest enough in them to finally empty them and I'm going to refill them today, but I completely refilled the black ink and they're still working. I suggest you watch some ink refill videos to get familiar with the process. Wear gloves and have plenty of paper towels on hand as the ink can get dirty.
