The colors that are inside this kaleidoscope are very pretty. I gave this to my niece and she loves it. Played with it for the rest of the day. She was captivated by the bright colors and how it is never the same way twice when you twist or shake it. It even has a printed background for the negative space.The bright pictures on the outside make it very kid friendly too. #rankboosterreview #Sponsored #LikeKingMong https://www.amazon.com/Kaleidoscope-Classic-Educational-Perfect-Colors/dp/B073YTDRF7
