It is a wall sticker that expresses a fashionable city with castles and houses with building blocks, like a foreign townscape.
Gray is a very cool color, and I recommend sticking it up in a child's room because it can be enjoyed for a long time, but it's also nice to stick it up in a place where adults spend time, such as the living room.
It is a wall sticker that not only children but also adults can fully enjoy.
Gray building blocks will tighten the walls in any interior.
