My little nephews has orbeez collection and he loves playing them around. He always stack them in a bottle according to their color and seeing them that are filled together makes them more cute. He’s planning to buy more orbeez and probably stack them again or he can buy new cool bottle for his Orbeez Refill addiction. I hope this time he can find other colors aside blue, yellow and red. I’m hoping he can find green and purple which makes it a good combination color.
