Some time ago I bought a set of city walls from Rubicon Models. I thought it was a great set and not expensive at all, so I decided to give It a go.
The box included four identical sprues, enough to make Up to 60 cms of walls.
All the parts of the walls fit each other perfect and it´s quite easy to assemble, but I used some glue to make a tough piece.
As most of the terrain pieces they are quite easy and fast to Paint, and once painted they look top on the gaming table.
I took pictures of the walls besides a 28mm miniature from Black tree (the same size as warlord´s miniatures) and they look top side by side.
I think it´s a great product that adds an awesome detail to any gaming table, and that it isn´t expensive at all, I think I just paid 15€ for the box.
