A set of 18xx tiles of your choice. You decide which tiles using established numbering or by describing your custom designs. Upgrade your train-game experience! Tiles are professionally printed on letter sized glossy cover stock which is mounted on 1mm matte board and then laser cut. Using standard 38mm (1.5") tiles, one order will produce 32 tiles. Note that there are unusable tiles on sheets specifying more than one background colour. Never run out of gentle curves again!
