Embark on an exhilarating journey into the world of baseball card collecting with the Slabs of Heat Baseball Card Collection Builder (or Starter Set!) Specially curated for both avid collectors and newcomers, this unique gift set is your gateway to owning a piece of baseball history and adding stars to your collection like Shohei Ohtani, Ronald Acuna Jr, Mike Trout, Aaron Judge, Fernando Tatis Jr, Mookie Betts, Juan Soto, Hall of Fame Legends, etc. In each box, discover the thrill of unboxing and "ripping wax" with 8 sealed packs of modern baseball cards, each brimming with potential treasures. Over 95% of packs will be from 2020 to present day (2021, 2022, 2023, 2024) so you don't have to worry about the 1980s and 90s "Junk Wax" packs that our competitors stuff their boxes with. Each pack holds the possibility of uncovering rare finds such as autographs, shimmering refractors, serial-numbered parallels, game-used memorabilia, and sought-after patch cards. We feature packs such as Topps Flagship, Bowman, Bowman Chrome, Bowman Draft, Topps Chrome, Heritage, etc! We only include MLB Officially-licensed trading cards from the Topps brand. In addition to the mystery of opening 8+ sealed packs, we include an ALREADY GRADED Mint Condition card graded by PSA or BGS with a GUARANTEED GRADE of 9 or better (potential for 9.5 or 10 Gem Mint!). This card will have the potential to be a Rookie Card, Autograph, Refractor, Serial-Numbered Rare Parrallel or other Short Print which gives the mystery box an added layer of thrilling excitement! To ensure your treasures remain in pristine condition, we've included 200 high-quality penny sleeves, offering the perfect balance of protection and display. Some boxes will even include surprise extras such as super-premium packs, extra packs, extra graded cards or other surprise items! It's time to "Step Up to the Plate" and "Swing for the Fences!" by adding this to your cart before you Strike Out and it sells out!
