Coasters - Vacuum Tubes

Set of Six

We have had a lot of fun developing our Vacuum Tube Coasters. Each one has a celebrated valve with some basic trivia engraved around the perimeter. They are made from 1/4" Baltic Birch and then laser engraved with original artwork produced by Fern & Roby. We love furniture, we love audio, we love beverages, and the vacuum tube coasters combine all of these things :)
