A stress crack to either side of the hinge, a small nick to either side further beneath the hinge.
5cm below button. Hinge and opening clasp work as they should.Although the cause of the faults highlighted do appear to be from the item actually being used, with the odd mishap. There area couple of small anomalies in the mother of pearl shell decoration in the front of the case, looking under a magnifying glass this appears to be a blister in the material.All faults can be seen in the images on line.All mother of pearl inlay appears to be intact
