Hey guys, I was searching for ink cartridges (specifically CZ638A) but at the same time, I came across CZ638AA (double As).
I've tried searching the difference between the 2 to no avail, so I would like to ask the differences between the 2 models (CZ638A vs CZ638AA) both cartridges have number 46 on them.....
Any help would be much appreciated !
Thank you for hearing me out !!!

The 2nd letter should be for a region ink cartridge is intended to be used e.g. CZ638AA and CZ638AE are the same but for a different region. Just buy your ink locally and you will be fine.
