These are metal-cast windows with detail on both sides - so you simply cut out a hole in your building wall and push the window in to place and - voila! - job done - a great looking window with detail on the interior and exterior sides!
They are designed for 28mm gaming sizes and materials around 5mm thick, although they will work with thinner and slightly thicker boards.
There are 10 different types: 6 'wooden' and 4 'stone' and they cost from £0.17p to £0.80 each. They are available individually so just use as many as you need without having to worry about pack sizes.

There is also a set of 6 (somewhat humorous) Gothic Corbels - Corbels are what were used on medieval buildings to help support beams as shown on the images below - and they can help transform a good wargame building in to a great one. A set of 6 corbels cost £1.20p

All the above were originally sculpted by Werner Klocke of Freebooter and Reaper fame.
