i have to add that reinserting the pin esp. for 0.1, 0.15 is a tactile affair. go to a happy and quiet place in your mind. roll the pin to check if it is straight and centered before reinsertion. feel for the tiniest bit of resistance cos this means the pin is not going through the hole of the point.

regarding cleaning, warm water, blowing, sucking are some helpful techniques learn and teach this to the ladies. not so much with sucking cos IDK about the toxicity of the ink and not so cool with the black lips, unless for the goths. here's the kicker, iirc use a drop of baby oil with the ink. i forgot why. sigh, too many jokes

thanks btw. i'll revisit my set and do some maintenance.
