I've added a new set of 25mm round Trench Board bases to my store, to go with the other Trench Board stuff I've been adding to the Wasteland II series.
RBWL2TB-001 25mm Trench Boards Set One 10 for $10.00 USDYou can find them at dragonforge.com.
Here is an image of them, I've kept the metal plates and bits off this set, as requested by those who would like to use them for WWI figures. Set Two will have more metal plates and bits on them. I will also do set 2 on the 40mm here soon, with no metal bits.
