My friend, David, just recently started a site that sells 25mm button badges. The site is YumBadges.com.

Right now, he has a bunch of cool designs with funny sayings and cool graphics.

If you have a design already or need a custom design, David can help you get it on a badge.
These are great if you have something you need to promote - maybe a business or an event.

Anyways, check out his site.
