The first annual team set from BBM this year was the Swallows. BBM is going with a standard set layout that you'll probably see 12 times in the next few months.
Six cards per 400-yen pack, 20 packs per box, 12 boxes per case. This set came out in early April.
81 cards in the base set:
The standard 18 insert cards are split into four different sets.
All four insert sets can be found in three flavors of parallel: gold #/90, holofoil #/75, and gold holofoil #/50.
Moving on to autographs, there are several varieties, similar to BBM's offerings in the past.
I don't have a sample image, but BBM again included Rookie Autographs for eight players, each numbered to 10 copies.
No new ground broken here, but I definitely love the look of Picturesque.
