McFarlane Toys/Halo Avatars Series 1
From Halopedia, the Halo wiki
Halo Avatars Series 1 is the first in McFarlane Toys' line of Halo-themed Xbox Avatar figures. In order to represent the customization options avalible for online avatars, the figures feature interchangeable heads, torsos, and legs. The line also includes various "prop" items, such as the Warthog. The figures are 2 1/2 inches tall, and are randomly packaged in small plastic cylinders, the tops and bottoms of which can be removed and used as a display base. The tubes themselves can be connected to form multi-level displays. Series 1 debuted in Fall 2012.
Each tube is packaged with a slip of paper detailing the figurines in that particular wave on the inside and an identical warparound outer cover with the bar code. There are no codes or markings on the outer slip that can enable you to discern the identity of the figure inside. This practice is referred to as "Blind Box" or "Blind Bag" packaging and is a popular practice in many collectible minifigure lines.
