Yes/no. This is a set that will help reflect your agreement or disagreement. Your emotions, state, mood. This set consists of 170 parts. Therefore, there will be no problems in assembling. The main colors are green, red, white and black. To change the sign you just have to turn the block over and you can show what you want! I built this model because I wanted it to be easier for people to express their emotions without words! This set is great as a gift. And to decorate your room! Many people for a long time were looking for something similar.
