These are ceramic magnets. They are a cute size, 5x5 cm. They are magnets featuring famous scenery and other motifs, drawn by illustrators residing in each prefecture across the country. Currently sold out (the Niigata magnet is currently only sold in Niigata), this is a set of the Bandai Bridge magnet from Niigata, which I was able to purchase the last one of the other day, and a cute Japanese map magnet. Perfect for collectors or as a memento of Niigata.
