This is a great looking set of rectangular dungeon rooms. The artwork is excellent, and reminiscent of the art found in classic RPG rulebooks. The sections feature plain gray tiled floors with cracks and shading. A wide variety of room sizes are provided – 2x3, 2x4, 3x4, 3x5, 3x6, 3x7, 3x8, 4x5, 4x6, 4x7, 4x8, 4x9, 5x6, 5x7, 5x8, 5x9, 6x7, 6x8, 6x9, 7x8, and 7x9. Each room size is presented in six configurations of one-square entrances/exits, allowing for a wide variety of arrangements (and some creative cutting and pasting could provide many more). The rooms are plain, so you will have to add your own doors and features (doors can be found in some of their other OSD products).

This product merges well with the other products in the OSD line, and it's a solid and versatile product for a very reasonable price.
