They are light but strong and they sure won't crack into a hundred pieces if they are dropped. They also won't chip if they are knocked like resin terrain does.
I'm going to buy a bunch of them and see how they look painted and flocked because the price is so unbelievably cheap compared to buying heavy resin terrain.
I have four hobbit holes I adore in resin but they are heavy and would shatter if there was a mishap and they were £25 pounds each.
I could get ten of the Amera pieces for less than that and enough change to buy the paint and the flock etc.
I love the fact they are light as well because I travel to play games around the country and it's going to be great to do it with cheap lightweight terrain that can stack in the same single box.
I'll report back to let you know how I get on.
