I ordered a wiring pen at aliexpress. The included rolls with wire are 0,01mm and 0,02mm which feels way to thin for me. Mainly because it is hard to work with without accidentally ripping the wire.
I found wireing wire in another shop with thickness of 0,13mm or 0,35mm, but only 4 or 5 rolls in a set. I really dont need 40 oder 50 Meter. And it is expensive.
Never the less I guess 0,35mm would be to heavy - right?
