The wood is 4" square and 1/4" thick ash, cut by hand on a scroll saw. It's finished with 3 coats of a water-based polyurethane for water resistance, and backed with 1/8" thick cork hand-painted to accent the design - these deskorations can double as coasters! Ash wood grain is quite variable so each deskoration is unique.
Be sure to order a deskoration stand (see all 3 in the last photo) so you can display your mining ship logo on your desk or mantel - you can find the stands here: https://centuryartisans.com/products/deskoration-stands
