Glass Etching is an excellent feature for any Shadow box or Flag Case! All of our Shadow Boxes and Flag Cases have a real Glass Window and some enhancement can be made by etching an Insignia from your Service Branch directly into the glass. This effect works best with larger images (4″ or larger) on a simple background. We suggest Etching your Army, Navy, Air Force, Marine or Coast Guard Insignia directly onto the glass of your Flag Case. Adding Gold or Silver Fill is recommended for etching that includes text, and looks really great when applied to your flag case glass. Glass Etching offers a subtle decoration to your shadow box or flag case. Highly detailed images can be used to add this effect.
