Somehow Woot still has a supply of the Smart Keyboard Folio for certain 11" iPads Pro/Air.

My wife is still using an older gen 11" iPad Pro and her keyboard folio stopped working (they fall apart after a few years ), so I took a gamble and ordered one. It arrived in the original, sealed packaging. As far as I can tell, it had never been opened, and it is perfect condition and works great. My wife is very happy. I bought a second one for when this one falls apart.
