We've created an universal sensory busy panel with a lot of developing, interesting and useful elements. The size of panel's set base is 25" x 69" x 2" (65cm x 175cm x 5cm) The entire set consists of 5 developing panels. All you need is to find a free space on the wall, drive a pair of sturdy screws for each panel and hang up the panels on the wall. As a result, you'll get a huge and interesting simulator for the development of your child. With its help your child will develop coordination of movements, hands motor skills, logic, will learn the colors and their mixing, learn the count and how to deal with clasps and how to manage with elementary locks. Playing tic-tac-toe will be interesting even for adults. If you want to customize panels' colors, please pick "Custom colors" option in a dropdown menu and put your customisation request into comment to the order. These busy panels will be interesting to any age, especially children from 8 months to 4 years. You can write us your individual wishes, we will develop for you any other panel. You can also request a personalization of products and we will offer you all possible options.
