This is a set of four coasters made from solid beetle kill pine wood.
Each coaster is 4" square with a 3" circle in the center lined with a bit of cork for absorbency. They are 1/2" thick, but with the chamfered edge they look thinner.
The particular coasters shown in the pictures are a random dozen from the first batch that I made. The coasters that you will receive will be similar, but I can almost promise that they won't be these exact coasters.
