I have a bunch of small buttons that I had made up for a talk at a business school. They are kinda cool, but I have more than I need. I'm selling them in sets of five for about 50 cents each. I can fill larger orders if you want more, or smaller orders if you don't mind the postage. They are a good size for wearing with a suit without looking weird. And they have a feature that allows you to level them after pinning it on.
You can buy them at biddingpond (link below), or PM me here.
Cheers
