I like the look of a wood grain, which means even my more modern stylized furniture tends to favor wood as a material over glassother.  More often then not though this means on a product such as this I get something that is actually a wood print.  That's not the case here.  These are a simple product sure, but the grain is beautiful and natural on every piece, and with the finish they're a very affordable and presentable coaster just in tune with my tastes.  Also they easily stack one into the other.
