For those who like a little mystery with their hobby, the Fanatics Under Wraps 2017 Next Level (NXTLVL) Edition has arrived. The Under Wraps product was one of the better sellers for the company during its 2016 debut.

Each box contains an autographed baseball from one of five “levels”: Debut Level, Premier Level, Legendary Level, Mint Level and Game Day Level.

Every ball from the Under Wraps NXT LVL has been authenticated under the auspices of the MLB Authentication Program.

The balls are priced at $199.99.
