By the way, my dictionary defines "mega" as an adjective meaning very large or huge. This box only had 7 packs in it for a total of 48 cards. This is not even as many cards as are in a normal blaster.
The set is a 50-card parallel of 2016 Topps Update using the extra-sparkly Chrome finish Topps has used on the past several years of Update Chrome. I'm pretty happy with what I got. There were 4 base cards, 3 rookies and one insert.
There are only 3 inserts in the set, and only one of them is a non-relic and therefore likely to be in the megabox.
Henderson not only got his 3,000 hit in 2001 with the Padres, he also set the career record with his 2,063rd walk. He has 2,190 walks for his career but has been passed by Barry Bonds who has 2,558. Here are the 2002 Topps cards commemorating Henderson's 2001 achievements, in real time, so to speak.
