Build an imaginary kingdom with the Magnetivity Magnetic Building Play Set Medieval Castle! Magnetivity encourages kids to experiment, explore, and imagine by inspiring them to design and build their own unique worlds! The 14 double-sided panels with artwork on both sides magnetically attach in different combinations, so kids can build new designs for their castle every time they play. The 63 included magnetic accessories stick to the panels and to the five magnetic play figures with stands, inspiring open-ended, hands-on exploration and play! All Magnetivity panels are compatible.
