Cardboard Miniature Stands

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 Kicks
