You simply MUST catch them all, darling! 1.75″ round magnet, comes in regular pokeball, or in ultra ball or master ball varieties.
This is a “flat” magnet, about 1 mm thick. They are not super strong (more decorative than utility), it takes 2 or more to hold a regular sized piece of paper on a magnetic surface. The magnet is wipeable and waterproof. All magnets are individually die cut and measure approximately 1.75″x1.75″.
