Bought a couple of these push pins mainly for the look, but the quality was very poor. I just tried placing a couple of them to the cork board, and they bent to the side. The ones that were able to be pushed did not go in as easily as other push pins. Of note, the part that actually goes into the cork boards seems quite shorter than the typical push pin. So...look is nice, but otherwise, I would've settled for regular push pins for the price.
These push pins are so popular that mine are gone. I ordered 4 sets of 12 (if I recall correctly) and the family and friends kept commenting on them and some folks actually asked for them. <g> They are resonable in cost so I gave them out in less than a week. Didn't get to use them. So can't comment on that. Darn.
The plastic is a bit crap looking for the price, but you can barely tell since it's small. It would be cool if they were at a jaunty angle so that it would be funny that they were random screws sticking out, but they stick out head on which kind of defeats the humor for me.
