What is the difference between the jumbo kit and the other kits of our product line?

The jumbo inkjet refill kits offer the most for your money. The jumbo inkjet refill kit for HP ink cartridges contains an 8 ounce bottle black ink and 4 ounce bottles of each color ink. All other ink refill kit brands contain of 4 ounces of black and 4 ounces of color. Jumbo ink refill kit sets are also available for most photo inkjet printer cartridges. Jumbo printer ink refill kits also include separate needles and syringes for each color, any special tools needed to prepare your cartridge, a pair of latex-free gloves and, of course, illustrated, step-by-step, easy to follow instructions. Most jumbo printer ink refill kits will provide you with at least 8 black refills and 15 color refills. Some printer ink refill kits, depending on brand and cartridge, will contain enough ink for many more refills or possibly a few less. The amount of refills depends on the cartridge size and how low the ink level is when you refill your cartridge. Tip: Never let your cartridge run completely empty! Always refill an ink cartridge when the ink level is low enough to show skipping or fading on your print outs.
