Review on 🖨️ High-quality BCH Refill Ink – Black for Inkjet Printer Cartridge: Bulk-Saving Solution – 500ml Bottle (16.9oz) – Standard Grade, H Series by Bret Wong

Before you try to refill a cartridge, watch the YouTube video and don't rate this product badly because you don't know how to do it. First I had to go in and disable the cartridge guard. When it's time to refill, you should gently poke the inside of the sponge with the needle and SLOWLY push out the ink. Before use, leave the cartridge for 10-30 minutes to allow the ink to disperse in the sponge. Look at the fill size for your cartridge and don't overfill it.
