Each pack contains two small pieces and one large piece. The smaller pieces are approximately 160mm long and are 25mm high arranged in a row. The larger piece is approximately 160mm long by 50mm wide. There are a range of variants for each piece so with a couple of packs that gives some varied options. If you look closely at the pictures, you can see that the top and bottom row pieces from each set of three are different.

The minis used for scale reference are all mounted on 30mm bases and are nominally from ranges between 32mm and 35mm.
