Impress your friends & family with your knowledge of Voronoi patterns.  This set of three coasters includes Poisson, Monte Carlo & Double-Poisson distributions.  

Each coaster has an inside diameter of 75mm to accommodate just about any glass.  Stretch by 25-30% in your slicer to fit wine & water bottles.

The coasters stack well, and also stack with the spiral coaster, origin for the remix.
