NOTE
You have to remove check valve on the cartridge for the adapter to work! Search youtube for instructions

With this adapter, you can easily refill your cartridge, of course after removing the check valve. Watch movies on youtube.  

With this metal adapter, you do not have to sandpaper plastic adapters to make them work. And they usually work quite poorly. And this metal adapter also does not break.

Also works on Babyliss cartridges

Includes adapter and 2 extra orings

Watch this clip when i fill an empty cartridge using this adapter, in just a few seconds.
