3.5" HDMI Screen Protector Source?

[obsidianspider]

I've seen a few people using the KeDei 3.5" HDMI screens and they look like a nice fit in a DMG, but ivanretrobit has also got a really nice screen protector on his builds. He doesn't really give out information on how he makes his projects, since he sells them, but has anyone seen these (assuming glass) screen covers for sale? They really finish off the project.
