Hi,
In my opinion it is depends on the manufactures. Different manufacturers have different parts to their ink refill kits. Here is a list of component that comes in any ink refill kit.
1. Ink – Obviously, you will need the bottles of ink for your refill. For black ink cartridges, you will need only the black ink bottle. For color cartridges, you will need each of the three pigments.
2. Injector – Most ink refill kits come with a syringe or other type of injection device. Proper use of these will make for the cleanest and easiest job.
3. Plug Extractor – The hardest part of refilling an ink cartridge is often opening it up.
