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 refill kits for HP ink cartridges contain an 8 ounce bottle black ink and 4 ounce bottles of each color ink. All other brands contain 4 ounces of black and 4 ounces of color. Jumbo kits are also available for most photo inkjet printer cartridges. Jumbo 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 kits will provide you with at least 8 black refills and 15 color refills. Some 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.
