Hate to be the proverbial stick in the mud, but there are plenty of items out there, fully licensed by MLB/MLBPA, and sold individually or in boxes that are not appropriate for this site.
I am not saying that these are inappropriate for the site, just that the criteria that was listed above is not the true criteria for this site.
