I had cheap pins originally, but fortunately learned my lesson with my glue bottle. I have a super-fine tip attached to my Elmer's glue bottle. Instead of removing and washing it out every time I use it, I simply stick a pin in the hole to keep it clear and stop it from drying out. It fits perfectly. One day when I pulled the pin out of the bottle, I noticed that it was a bit rusty. Promptly threw the entire box of pins out and bought nickel-plated pins. They also glide though fabric smoother. The cheapo pins feel like sandpaper when they go through fabric.
