Nap 818 (Green)

NAP stands for "Nintendo All Plastic". This series of cards is exclusive to the official Japanese Nintendo website. Nintendo has been selling traditional playing cards, simply known as trump in Japanese, for years. Before the days of Mario and other iconic Nintendo mascots, most sets were pretty standard, although Nintendo at one point did have access to Disney characters which they used to help drive sales of their products. Nowadays, Nintendo continues to sell these cards and occasionally even releases new sets based on Nintendo characters and series. There are a number of styles that the company sells all for pretty reasonable prices, usually between about 600 to 1,000 yen ($6 - $10 USD).
