I like cardstock miniatures for gaming, like SJ Games's Cardboard Heroes (http://www.warehouse23.com/products/cardboard-heroes-fantasy-set-01-player-characters). They're inexpensive, easy to carry and store, and save me the trouble of painting. But with their light weight and small bases, they've got stability issues. They blow over in a slight breeze and are easily knocked over if the table gets bumped.
These plastic bases, inspired by the ones for the Dungeon Fantasy Roleplaying Game Kickstarter, are designed to fix that problem. Instead of folding up a stand-up triangle, just pop the cardboard miniature into the base. Much more stable, and since it's folded flat, more resistant to crushing. They're sized for one-inch-per-hex hex maps, and include one-hex (for people) as well as two-hex and three-hex versions for larger creatures.
10/29/17: I've added a couple more since the initial upload. There's one for three-hex creatures with a triangle rather than straight-line configuration, and another which contains two figures in a single hex (for example, two characters wrestling or otherwise in very close combat).
