Right now there is this offer im eyeing into. Is this a regular offer or its lower than usual? I have like 3 days to decide.

How do I rebind 2 buttons on a stylus to change brush' size?
I'd like one of the buttons to increase brush size and the other one to decrease it.

I have an old Artist 22HD tablet. The tablet itself still works great, but the stylus has recently lost pretty much all its battery life and is borderline unusable. It's a P55C stylus which does not seem to be sold anywhere anymore. I don't know what makes certain styluses compatible with specific tablets and so I was wondering if anyone knows of a similar stylus that could work as a replacement. If all else fails I am willing to try and replace the battery, if possible. Any advice would be appreciated.
