I think is pine wood, but not sure. Not an expect, it is kind of soft wood, but not too soft. Bought two pieces of it 100 x 40 x 4 mm and 100 x 5 x 5 mm, it was enough for the bench I made.
That looks nice. I was thinking about some place I could put my screwdrivers, but I have only three for now And three tweezers only.
