Herman Miller Novelty Item This is a keychain featuring the Herman Miller logo. I believe the transparent part lights up when you press the black part. It uses two button cell batteries. I haven't confirmed the operation because I don't have new batteries. Please understand that it may not light up as it's an old item. This novelty item is over 20 years old and is now very rare. I used to like it and used it for a while, so the logo has some wear. The logo side of the transparent part has a smooth finish, and the back is frosted like frosted glass. The white line on the logo in the third image is a reflection and not a scratch. Please examine the images and consider purchasing only if you are satisfied.
