Not the original poster, but I can offer some pics and data.
I have one complete set and some loose pieces from another set.
Obtained both the set and loose pieces through E-Bay purchases.
The complete box set cost me about $20-$25 (Sorry, I do not recall exact price).
The loose pieces cost me almost nothing really; they were part of a large lot of mostly crap; with a couple of items I wanted.
My grandkids play with the walls, etc. occasionally along with some Dwarven Forge pieces and Miniatures but they never use the magnetic board.
The box set includes a square box (10-1/4" x 10-1/4"); one metallic board (10" x 10"); three different types of wall pieces; a TWO-sided instruction sheet; and a Flyer with suggestions (Blue Inked)
Box Top:
Board: 10" x 10", metallic with felt bottom. 100-One-inch squares (10x10) painted with the look of worn flooring in the paintwork.
Magnetic Wall pieces: 25 walls, 5-doors. Walls-short wall; tall wall; arched doorway.
All of the wall pieces have magnets glued to a groove underneath the wall pieces footing.
On smooth flat surfaces; the wall pieces can easily stand on their own without the magnetic board.
