I tested the distribution out on test with around 200-some of the things. You buy one booster, and open it. You get 5 randomized items, usually 2 commons, 1-2 uncommons, 1-2 rare and often (but not always) a very rare. All the items are "Character Item" emails, so you can get them on any character but only that character. I don't have an exhaustive list, but this is the things I've found: Common and Uncommon items are usually dual/team insps or 25/50 reward merits; rare are usually 100 merits, large dual/team insps, some ATOs, and Elemental Order pieces; very rare are 200 Reward Merits, XP boosters, Windfall temps, a few Elemental Order pieces, the more rare/useful ATOs, and Enhancement Catalysts. Enhancement Catalysts are combinable with ATO enhancements to make Superior ATOs. It upgrades their numbers and set bonuses from normal to purple-level. Note that they are counted as different sets, so if you catalyze some and not others, you won't get all the set bonuses.
