Thomann Nataraj Tanpura Bridge Male

In buying a blank bridge I would have expected a reasonably flat surface that I can then add as much curvature as i wish. The piece I got has an exceptionally uneven surface. Much more material on the left in comparison to the right, holes and dips in all the places you don't want them. All making for much more work to get it to the desired shape. Along with that the feet of the bridge were set unevenly and one shorter that the other so they had to be replaced altogether. The face of the bridge was polished, which is totally unnecessary for a "blank", unless its actually meat to be the finished article. If it is, that make this exceptionally poor.
