I am cleaning out unused items from my diorama days when I bought in bulk.
They have very nice detailing. Can be used for 1/35, 1/32 and 1/30 scale dioramas.
You might use more detailed trunk trees in the  foreground and build with these to get a 
really nice forest effect. As you can see there are three heights. The tallest is 11 inches high.
I will use the original Manufacturer's cardboard box to ship in.

I will not ship to Canada, please don't ask.
