Takara Japan Tomy Tomica Hashy Bus-shaped Digital Height Meter

This bus-style electronic height meter allows you to measure your child's height instantly at the press of a button—all you need is a nearby wall.

The method is extremely simple: Have your child stand against a wall and place the device at head level.
Then, have your child step away from under the height meter. Press the button and wait three seconds!
 
A beep will sound, and your child’s height will be displayed with an accuracy of 0.1 cm.
No need to mark walls or columns with paint, or use a ruler or tape measure.
With your beloved Tomica design, measuring height is now easier and more fun.
Parents and children can record growth together and enjoy the process.
