While I agree with others these cabinets are not as well constructed as the old cabinets but they are essential for a small shop. Many of the compartments I have, especially for cords and letters, are empty, but there are a dozen or more in the basic sizes, and since I need a new size I buy 5-12 bits and fill them up. If you're really working you need more than one bit because they will break, bend or dull, so indexes of the same size are a waste of time in my opinion.
