Sick of opening up "Mega Boxes" or "Hobby Packs"? Just like in the game a baseball, they are usually a swing and a miss. I personally became sick of it so I began making my own mystery packs to sell at local shows. After a few months, people suggested selling online and here we are. Each box is loaded with a value that often surpasses what you can buy in a store.
 
Each Baseball Mystery Pack will include the following: 
One Graded card from the list below
1 Sealed Modern Pack
One Autograph Card or Memorabilia Card
5 Rookies
5 Relics, Parallels, Inserts or Short-Prints
