This is one "Manny Rococo" magnet from Manny, a long-established general goods company. Although small, it holds quite firmly and is very convenient. The magnet is embedded in hard ceramic, so there's less worry about breakage, and it feels more secure than a magnet simply glued onto the ceramic. However, please be very careful about accidental swallowing by children. ❀ Size: Diameter 3.1cm x Thickness 1.3cm ❀ Materials: Ceramic, Magnet ❀ Made in Japan
