Is there anything worse than ring stains on furniture and table tops because you didn't have enough coasters for your guests? Yeah, I don't think so either. Be the hero who gives out coasters to employees and clients. The next time they have a party they'll be thankful you gave them such a practical gift. Heck, every time I use my coasters from Prague I'm reminded how much I'd love to make a second trip to the wonderful city. See, it really works!
