Popular cuckoo clock now comes with super sturdy wood backing! Quality of the wood panel makes its presence even more substantial while keeping the charm of the cuckoo clock exactly the same.Wood panel is birch laminated plywood, approximately 1/4" thickness (doubling the thickness of the previous chipboard backing!) The image is printed on Epson 2400 with high quality - fade resistant ink. The image is mounted on the wood panel using PH neutral adhesives (it's used in photo archival places) which prevents yellowing over time.Clock shown is 7 x 9 inches (bigger than previous clock). Custom color is also available up on inquiry. Clock requires one AA battery to operate.
