I made a keyholder out of an MD disc! It reflects a shimmering rainbow color depending on how the light hits it. It's become a stylish item with a retro feel. Since the disc isn't completely fixed, it makes a cute rattling sound. Because it's a keyholder, purchasing it for playback purposes comes with risks. Please refrain from doing so. This is a one-of-a-kind item. Please understand that this is a reused item and may have minor scratches. I have other MD keyholders for sale, so please take a look.
