Housing item question

[Arohk]

I've recently started watching decorating videos on the ol' YouTubes and have seen people using a white wall with wooden supports, like it's a big sign board. It appears to be most often used to lift/glitch items and/or for temporary wall/partition planning. What items is it?

Stage Panel, buy it from the basic housing vendor (or maid in your house)
