These are bamboo tablet or phone holders. Designed to hold your tablet or phone while charging, they have a recessed part that allows charging cable connection that I can confirm works with my iPhone and iPad with lightning cable. They are comprised of 2 separate pieces, and the back part is 5 x 7 inches. The one I tested holds my iPad fine, but I would suggest using these with a relatively small tablet or regular phone, since bigger tablets might be easier to knock over with these.
