Rocky terrain for the MINI-Z 4x4. A set of 5 pieces of 480 x 480 x 103mm terrain. Making a square with four pieces and putting the 5th one on the center of the square will make a 960 x 960 x 156mm terrain, and you can enjoy wide variety of terrain by rotating each piece. Even larger terrain can be made using multiple sets. https://rc.kyosho.com/en/mxw006.html
