This is a pack with 1 random shaped and sized hill​​/​​bluff​​/​​rock, depending on your scale. Sizing of pieces is random, but a typical selection is shown in the pictures and sizes are easily determined as the grid they are on is 1" squares. They cover approximately 1​/​4 square foot. They are 1" tall, with flat tops. Pieces may be sloped if wanted. If you desire any sloped pieces, an upcharge of $ 10 per piece will be added, please let me know when ordering.
