6 28mm Urban Bases.

1. Asphalt with inset water valve covers.
2. Ashpalt with a man hole cover. (Not that man hole!! sicko!)
3. Sidewalk and dirt.
4. Sidewalk and curb.

The two bases that have dirt are designed with the dirt slightly lower than the sidwalk so that you can just paint it as is, flock it, or add static grass. Bases are unpainted.
