The Pokémon Shiny Treasure ex Booster Box is a Japanese-language Pokémon TCG booster box from the Scarlet & Violet era. Shiny Treasure ex, identified by the Japanese set code SV4a, is a High Class Pack set released in Japan on December 1, 2023. The set focuses heavily on Shiny Pokémon and combines familiar Pokémon from the Scarlet & Violet era with a large selection of special and alternate card treatments.

Each Shiny Treasure ex Booster Box contains 10 Japanese booster packs, with 10 Pokémon cards included in every booster pack. This means a complete booster box contains 100 cards across its 10 packs. The larger pack size is characteristic of this Japanese High Class release and differs from many regular Japanese expansion sets, which commonly contain fewer cards per booster.

Shiny Treasure ex is particularly recognizable for its extensive selection of Shiny Pokémon. The set includes regular Pokémon, Pokémon ex and numerous special rarity cards, with Shiny versions forming an important part of the checklist. Pokémon such as Charizard ex, Gardevoir ex and many others appear with special treatments, while Art Rare and other higher-rarity cards add further variety to the set.

All cards inside the Shiny Treasure ex Booster Box are printed in Japanese. With 10 High Class booster packs and 10 cards in each pack, the box offers a different opening format from a standard Japanese booster display. Card contents are randomly inserted, so individual cards should not be considered guaranteed unless specifically stated by the official product configuration. The combination of Japanese printing, Shiny Pokémon and the High Class format gives Shiny Treasure ex its distinctive place within the Scarlet & Violet era.
