I use these bases to mount my Imagination forces on and then use resin gel to texture over them. They are nicely done and I now have several hundred in use. I also take a Dremel drill and cut out a small hole in them to add a 1/8 by 1/8 magnet as I store my figures in metal lined cardboard boxes.

I based a bunch of 15mm minis on pennies and only later realized that this was a mistake since pennies are non-magnetic and I really wanted to be able to transport my forces in a box lined with magnetic strips. The solution was to add the self adhesive flexible steel base bottoms to the pennies. Now they work just great with the magnetic strips and I can transport my forces. Thanks for the wonderful product!
