This is a bundle of Reclaimed Oak wood that has had tongue and groove run on the edges.
It's been surfaced a little on the face and also has been milled flat on the back.
The pieces are around 3/4 of an inch thick and 4 1/2 inches wide (not including the tongue) and range from about 36 inches to about 15 inches long.
As with all my stuff, what you see is what you get. So look at all the pictures and ask all the questions.
