As I see it - the new aspect is the fact they are cast in resin not rubber, to get a sharper edge - I agree it works better on some of the pictures not all(they did get their kids to paint up some of the examples)
This:
when green stuff has been applied to the whole pad, hardened and painted, gives you this:
- a 15cm wide base.
Don't forget they are designed to be used like this:
providing a huge amount of variety to your bases.
I should add, I have nothing to do with these guys, other than being in for 5 bases myself. Will be using them on my Empire of the Dead figures as well as re-basing my fantasy RPG figures.
