The base cards are high-gloss and printed on a premium stock, which is a step up from other premium box sets like Icons. BBM has been using this kind of stock for other sets, so it's not new. The fronts have lots of foil, while the backs have a sepia/black and white version of the front border and photo. Overall, the cards are appealing.
Shohei Ohtani unsurprisingly gets his own insert set - a two-card set titled MVP. One card shows him pitching, while the other shows him batting. Again, not a big surprise. I haven't seen these in person but there's lots of foil-on-foil action here. Each box has one of the two cards; the base version is numbered to 300, with 200 and 100 serial number parallels also included.
The other insert in each box is an autograph. There are more autograph subjects than base subjects, with each signer limited to 10-20 copies.
