Instant purchase OK. It seems to be an artificial flower for air purification. I read it on the package when I received it, but since it's not a machine, I don't know if it actually purifies the air. How about it as interior decoration? I received it and displayed it, but I'm selling it now because I'm redecorating after having it for about a year. It has a little dust on it, so I will try to wipe it off as much as possible before shipping, but there might be some that I can't remove completely. Please understand this before purchasing. The size is about 15cm x 15cm. It's a just-right size, so it can also be used as interior decoration.
