Philips made some nice promotional CD-i material like t-shirts, caps and bags, but the amount of accessories for your CD-i player was always limited. This dust cover is actually a very nice item to keep your CD-i player safe from dust. They sell it at Etsy, for around 14 dollar. If only Philips paid some more attention to this kind of items in the ninetees! For now, the 220 model is the only available version, but as the author produced a LOT more console dust covers, more CD-i versions might follow. It's nice to see CD-i is actually a part of his console range of covers :) - On the back, there's space for the cables so it fits really nice around your player..
While they already have lots of specific Philips CD-i merchandise at Teepublic, but this might be my number 1, if only I had a CD-i 220!
