Wizard World announced today a complete sellout of the first edition of ComicConBox, a premium monthly box service business that launched last week. As of next month, a limited premium subscription will be offered to fans.

First edition boxes are scheduled to ship within the next one-to-two weeks.

Luckily for fans, Wizard World also announced today that ComicConBox will shortly be offering a three-month subscription that brings an exclusive Marvel Secret Wars #1 sketch variant comic inside its next ComicConBox.

ComicCon Box was announced April 22 and joins an ever-growing list of specialty boxes including Loot Crate, Nerd Block, Nerd Block’s recently announced Comic Block, Power Up Box, My Geeky Goodies, and many more.

Expect a bubble to burst any time now and the fad to pass.
