This was a quick little development project we did for the Amiga CDTV.
The item is a couple of variants of the original accessory removal key that was provided with some of the expansion hardware available at the time for the Commodore Amiga CDTV.
Once these devices were installed in the CDTV, you would need a key to pull them back out. Without it, you risk damaging the CDTV unit as you'd have to pry the device out of the CDTV. This little key provides the user the ability to pull out expansions just like the original key did.
This set of keys (one deeper than the other to provide extra stability in difficult or stuck pulls are now available in the shop, under the Amiga category.
