Pokémon Japanese Gym Heroes Vintage Booster Pack. 
Packs are 100% unweighed and came from a childhood collection where the packs were purchased from the original owner who purchased them when the set initially released. 
Pack can be opened live on our next twitch stream, and all cards will be shipped to you after the stream, or can be shipped sealed.
