SmartJars are offered as rewards in 6-packs (a pack of six), 12-packs (a pack of twelve), and 25-packs (a pack of 25). There is one pack per reward tier. So, for example, the first tier is
"Pledge $25 or more" and receive "6-packs of SmartJars in one of the 6 standard colors. We'll ask you for your color choice prior to shipment."
For this pledge, you'll receive six jars, lids, and docks, all assembled into six, docked SmartJars.
