Below is the official description from Nintendo of Europe’s Stars Catalogue.
Know when to hold ’em and when to fold ’em!
These super-shiny playing cards, decorated with images of your favourite Mario characters and power-ups, are sure to make any card game special! Pack includes 54 semi-transparent plastic playing cards (52 cards, plus two Jokers). Measures approx. 6 x 9 cm
(Note: Due to the production process, some reflective material may remain on the outer edges of the cards, which may be transferred to hands after prolonged use.)
Personally I don’t have the points for these as I just spent 7000 on the Luigi Diorama when it got put back into stock on Nintendo UK’s eShop. Of all the collectibles we’ve seen from Big N in recent years whats the favourite one you own?
