Local Character Peko-chan Plug Mascot: Ranch Limited Edition Cow Fujiya This is a plug mascot that you attach to the earphone jack of your smartphone, etc. It features Peko-chan wearing a cow costume and holding a milk bottle. By inserting it into the earphone jack, it prevents dust and debris from entering. I have disposed of the packaging, so I am unsure of the detailed usage instructions. Please consider it as a strap. m(_ _)m
