I've had the same experience with the midwest pins. They are also very flimsy. I was gently pushing a pin through 1/16 balsa sheet in an 1/8" balsa wing, and the pin bent 90 degrees. Talk about a cheap pin.

I go to my local arts and crafts store and get pins by the 100 count and they come in a nice little plastic case. Now thats a bargain!
