Cosmological Cosmeticals:

During manufacture or handling, the surfaces of mirror blanks can acquire some scratches, or slight chipping at the edge - neither of which will have any effect on your mirror because you will be grinding out any scratches and bevelling the edges. Any blanks deemed to have more than slight scratches will be placed on our clearance mirror blanks page. All the mirror blanks we sell - regular or discounted - will all make a wonderful telescope mirror!
