These plastic push pins that come with a count of 500 are definitely worth it.They seem to last forever.I usually use them to hold up important work papers that I know I'll be needing soon but also use them for various personal items I know I'll need at dome point.Bottom line is that they are used often and worth every penny.Highly suggest them.
