Two Royal Air Force coasters. I'm unsure of the material. The front looks like leather, but it may be synthetic leather. The back has a brushed texture. The color is a burgundy, a brownish-wine red. The print is gold. Approximate size: Diameter: 9 cm Thickness: 3 mm I received these from someone in the military and have stored them unused for a long time. One is in good condition, but the other has a white stain. Please check the images.
