Big Shiny 1-UP is a Battle Sticker seen in Paper Mario: Sticker Star. When Mario uses this sticker, his HP will heal quickly over the turns. Like with the Big 1-UP sticker, the Shiny Big 1-UP is extremely rare and one could only be found in the entire game.
The Big Shiny 1-UP looks identical to the Big 1-UP sticker except for the silver background and the large size. It takes up four sticker spaces in the Sticker Album.
