the first 3 pictures show a smooth surfce while the last two show a rough surafce with many holes as you would expect from concerete. are the first 3 renders while the last 2 are actual?
there’s three options: smooth, green, bubble.
people can choose to purchase the one with holes if they want
also I think those are all pictures not renders since this already finished two rounds in China
edit: yeh just looked on zFrontier. actual product def smooth
