Puyo Puyo Balls 100g These balls expand to about 10 times their size when soaked in water. They swell into beautiful, pale pastel colors. The size is similar to that of a marble. I put the expanded Puyo Puyo balls in a container, put my hand in, and enjoyed the feel, and I also played with them in a water bath. When I put them in the water bath, the transparent balls became indistinguishable from the water, and it was difficult to find them in the end, but I had fun playing with them. I bought a lot of them, but I won't use them all, so I'm listing the unused ones.
