Includes 1 random color spring - These colorful metal magic spring toy is a classic fun toy. It is a good size for holding and letting it drop to the floor, and fidget in your hands. The spring coil is 2" tall and 2.4" wide. These are just a fun and calming fidget. Hold one end of the coil in each hand and slowly move each hand up and down and watch the coil form a rainbow that moves back and forth. This is also a perfect toy for calming and self regulation. It makes a mesmerizing sound as it falls back and forth. Keep hands busy! Sorry, these are not big enough to go down the stairs.
