i've had a few questions about mine, so i thought i'd try to make an informative post about them. there's three main ones i get when i am there:
Drawer Organizers ($1.25 for one of the med and long, two of the small):
these come in three sizes, are very versatile, and are shorter than the other two to make that step look
Three space organizers ($2):
fairly big, good for displaying three deluxe-voyager sized figures comfortably
Photo Cube ($1.25):
they are about the same size as the Three space ones, but they're perfectly flat on top, something that helps with figures like G1 Magnus or Rodimus Prime's turret. These come in pairs and slide together to form a cube, i just picked them up for the first time yesterday, and am very impressed with the results they give
some examples:
