Not too springy or well made

I've tried a variety of springs from various ballpoint pens and these ERDANER springs perform exactly like those. Not too soft and not too stiff, these are just right. Works brilliantly for all your hobby/maker needs.It's actually a bit cheaper to buy lots of ballpoint pens in bulk and then use the springs from those, but I can't in good conscience justify creating yet more landfill.
