BBM celebrated their 35th year of doing baseball cards in 2026 and late in the year their parent company, Baseball Magazine Sha, published the 4000th issue of Shukan (Weekly) Baseball magazine. To commemorate both of these occasions, BBM issued a set with the somewhat unwieldy name of "35th Anniversary & Shukan Baseball 4000th" or something like that. The set was originally supposed to be released in December but it ended up getting delayed for a few weeks and didn't actually make it into the stores until early January.
