Hey Safire6,
I just saw your post—I'm from Hungary, and one of my friends has the same cabinet as yours. He found a local company that was able to cut some extra glass shelves for him.
I know we use different measurement systems, but since the sizes are in millimeters, you should be able to easily convert them to your preferred unit.
The new glass is a slightly tighter fit, but it’s perfect—it doesn’t wobble like the original one.
