Using the Grimm's large 12 - piece wooden rainbow is super easy. Let your child use it to create all sorts of things like bridges and houses. For younger kids, you can help them sort the pieces by color or size to develop their skills. When your child is done playing, make sure to put the pieces back in a safe place so they don't get lost. To keep the rainbow in good condition, clean it with a soft, damp cloth. Avoid using harsh chemicals as they can damage the safe water - based paint. Remember, this toy is for creative play, so encourage your child to come up with their own ideas and have fun!
