Quality / price very honorable. On all used CD (two boxes), I have never met a concern for writing or reading. For their time, I will complete my review every 30 years. Just a small warning on the closing of the box: the taking by the cover, and all the weight residing in the database, ensure the correct position of the closure flaps to avoid any pick up on your desk, or on your feet. This inconvenience has happened to me several times, fortunately the "off" or a few centimeters above the plate in my office, phew. A closure click would be welcome.
