ONE PIECE Card Game Promotion Set 2025 Sealed Mcdonald's Promo 6 piece set

This item is most likely the exclusive *One Piece* McDonald's promo pack (sealed) or the official *One Piece* promotional card set from Bandai Namco.
These special booster packs were distributed in Japan as part of limited-time marketing and sales campaigns. Since they are not available through regular retail channels and contain exactly six strictly limited promo cards in original sealed packaging, they hold significant collector value.
