This video shows an HP21 ink cartridge being refilled, but the HP 300 is exaclty the same method, and is basically the new HP 21.

The colour versions are different though, so be careful to check the above link, to see proper instructions.

You just need to buy a, "ink kit", which you can find by searching "ink kits".

The truth is, you just have to be very careful. You wont normally get more than 5ml in.
