LD Tumble StackerThis playful wooden tumbling ring stacker for kids is designed to develop their hand eye coordination through fun and hands on play. Children are encouraged to place the wooden rings in the correct order and stack them on the pyramid. That's quite a challenge, because the pyramid tumbles back and forth. Keep trying, you can do it! Made from FSC certified wood. Age: from 12 months Washing instructions: only wipe with a slightly damp cloth.
