A nice product for old-timers like me... A box of prepainted, configurable dungeon walls and doors. Each box has 50 wall sections and 5 wooden doors for 25$.
This is the manufacturer's siteAnd an official example:
Some weeks ago, my order arrived and yesterday I took some photos
Here are the two boxes
Once opened, each box has a plastic bag containing the pieces
Walls and doors are prepainted. Not a good standard but acceptable for a game. Pieces can be fixed two by two and then you can bend the walls or create corners. The manufacturer recommends to create some 3-4 wall pieces in order to quickly set the dungeon during the game.
An evil empire dwarf serves to get scale info
When the walls are combined with tilesets, the effect is great. D&D and Heroquest games are really enhanced.
I will use these walls to make the Nazi Prison escape from Amazing War Stories. I will post pics when I manage to play it.
