The pencil portion of the #7kp handle is about useless.
It uses some sort of nuisance "non standard" lead size.
0.9mm lead is loose and falls out and the next standard size of 1.3mm will not fit and is far too big.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
