About
Welcome to GrandVaultTCG – Built by a Collector
We founded GrandVaultTCG in December 2025 as a true passion project. Trading cards have shaped our lives for years. We know the feeling of opening a fresh booster box and the pride of adding a strong single to a binder.
We built this shop for collectors like us. We focus on authentic Pokémon sealed products and Pokémon singles for sale. Every listing reflects what we would expect from a seller.
How It Started
GrandVaultTCG began with our own collection goals. We searched for clean boxes, strong centering, and cards worth holding onto. That search led us to build a shop that meets those standards every day.
We focus on premium Japanese Pokémon booster boxes, including:
Sealed Pokémon Munkies Zero
Japanese Mega Dreams
Japanese 151 booster boxes
We protect sealed products to keep wrap tight and corners sharp. We inspect singles for edges, surface, and centering before we list them. If we would not keep it, we do not sell it.
Collector First, Always
We run GrandVaultTCG with a collector-first mindset. We care about clear photos, honest condition notes, and fair pricing. We maintain a 5-star selling history on TCGPlayer and follow strict listing standards.
Our inventory includes Pokémon singles for sale across many sets. Popular cards such as Mega Charizard EX remain in high demand. If you need a specific card, reach out and ask about availability.
Rooted in Roscoe, Serving Illinois
We operate from Roscoe Illinois and serve collectors in Loves Park and across the state. Many local collectors struggle to find sealed Pokémon products without driving far. We provide access both online and through local support.
We plan to grow into a physical storefront in the future. We want a clean, organized space where collectors can browse sealed Pokémon Munkies Zero, Japanese 151 booster boxes, and strong singles in person.

Our Vision for GrandVaultTCG
We see GrandVaultTCG as more than a store. We see it as a steady presence in TCG sales Illinois collectors can rely on. We will continue to expand into Magic, Yu-Gi-Oh!, and One Piece while keeping Pokémon at the center.
We focus on trust, care, and long-term relationships with collectors who value quality.
