So much fun to fidget spin the base one way and watch the arms form a tree, spin the other for DNA strand/cobra look. The sound and motion are captivating. This is a pen for the ultimate fidget fan. Choose from 1 of 3 color schemes, pink, yellow pastels, rainbow brights, blue, green and purple pastel. Any one you choose, the fun is exactly the same. Each pen writes with blue ink and the point can be twisted back up inside. When the ink finally runs out-the fun fidgets on.
