Part from Dungeon Floors set by Heritage Miniatures Company, vintage (1980's); this one is a straight stone staircase.  Made of light cardboard.

Matches 25 mm scale; roughly 2 inches long.

Good condition; edges are slightly irregular, since they were cut out by hand with a scissors, and have noticeable wear (see pictures).  The item is NOT folded along the stair edges.  

Can be used with Dungeons and Dragons or similar role-playing games, in collage art, or in a dollhouse.  No, I did not break up the set to make more money selling parts; I'm keeping most of the set, and selling parts of it.  

Sorry, no international shipping on this item (I am selling other items I can ship internationally).  If you are OK with me sending this in an ordinary envelope with a little extra padding, weighing less than 1 ounce, I can ship it with a stamp and refund the shipping charge.
