J4aime this box because it is strengthened and lempêche from sagging. The quality is top, the closure is very easy. Small flat on pre-cut inside location. They are poorly designed and do not let a protection on the bottom. The pieces are in contact with the hard side of the box. I cut small piece of foam to put at the bottom of the slots. In addition, the locations are not helpful. I would rather cut myself these locations. Nevertheless, I recommend this box.
