In 2014 I seem to have found plastic hex bases somewhere(I recently reopened the box where I stored all the Battletech stuff I bought in 2014. Some nice surprises in there!) The bases are in pack of 10 and there is a small insert in them that has 2 logos, one is RPE and the other is IronWind Metal. But I cannot find those plastic bases on IWM website. Have they stopped making those?
