Type Cover
Created by Microsoft, the Type Cover is a computer peripheral used with their portable Surface line of products, including the Surface Pro and Surface Go. As the name would suggest, the Type Cover acts as a foldable screen cover and a keyboard. It connects to Surface devices using magnets, allowing it to "snap" into place and be detached easily.
