The first few times I refilled a cartridge it was messy but with practice it was cleaner and cleaner.

Especially if it's using invisible ink. <G>

I once had a "spy" pen that came with invisible ink.
I would write something and moments after I wrote whatever (or any other word for that matter) it would slowly disappear.
Had to to read it under some special light bulb IIRC.
That would be handy for messages you don't want anyone to read.
Provided the receiver had a special light bulb as well.

Now that you mention it, I think I had something similar. It looked
like a dim or very light yellow.
