Cultivate imaginative playtime fun with the Magnetivity Magnetic Building Play Set On the Farm! Magnetivity encourages kids to experiment, explore, and imagine by inspiring them to design and build their own unique worlds! The 16 double-sided panels with artwork on both sides magnetically attach in different combinations, so kids can build new designs for their own barnyard and tractor every time they play. The 77 included magnetic accessories stick to the panels and to the six magnetic wooden play figures with stands, inspiring open-ended, hands-on exploration and play! All Magnetivity panels are compatible.
