From their announcement:
Toshach Miniatures’ Road Packs are designed to add realistic roads to your layout at a fraction of the cost you would spend on rubber, plastic, or resin road terrain. Road Packs are available in three scales, 15mm, 10mm, and Micro-Scale (1:285/6mm). Each Road Pack includes straights, curves, and a variety of intersection types in three surface textures: paved, cobblestone, and dirt.
Any number of Road Pack components can be spliced together or cut apart to create or fit an almost unlimited number of layout variations. Original and photographic textures have been incorporated to insure a very realistic appearance on your battlefield. Each Road Pack is available as a pdf download for $5.00.
