Having a coaster set on hand can help prevent your desk or living room furniture from enduring possible ruinous water stains that can be left on accident after someone sets a drink onto a bare piece of furniture. At BizChair.com, we offer some of the finest leather coaster sets with holders available to help prevent such a problem. They are 4 inches in diameter to cover your average glass and come in different tones of leather. Sets of 4 coasters make great gift ideas, too. Plus, if you act today we can include free shipping on most of our coaster sets!
