This is one of the coolest products I have seen in a while. Small tile mats that are made of real some sort of ceramic tiles. Perfect for basing etc. as the base is flexible paper. Available in multiple scales and The sement to fill caps is also included in the pagake. More info is at their website. They have also single tiles if you ever need small tiles.
I bought mine from ModelbahnShop Lippe, excellent fast delivery. They have a good selection of model railroad and scenery stuff.
