Quoted from vid1900:If you want to magnetize these, stand them up on a speaker magnet for a few days.
Or get one of these magnetizer/demagnetizer blocks, they're pretty useful for a few bucks. https://www.amazon.com/Wiha-40010-Magnetizer-or-Demagnetizer/dp/B00018AONE/ref=sr_1_2
Quoted from Shredso:I've never worked on a game that was manufactured outside of the USA. I wonder if they will be using metric.
Of my three Euro-made pins, Lebowski and Full Throttle are metric. Don't remember with the Playmatic, but I think it is.
