Wanted - Givi Topbox

After a Givi Topbox, specifically looking for a monokey one

If you have anything else that might be appropriate let me know. I’m going to mod a spare seat for my bike to make for easy commuting

Might have one, cheap and with installed LED brake light (optional)

Mine is the one with the two prongs coming out of the back of the box, is that monokey?
