When buying a briefcase, please pay attention to the following signs of quality workmanship:
The stitches on the bag should be straight, even, small and without loose threads. Check that the inner and outer surfaces are consistent. Reinforced stitches protect the fragile areas of the bag.
Metal zippers have better quality than plastic zippers. Open and close the zipper several times to ensure a smooth closing. If you are shopping online, please check if there are pictures showing the zipper closed and opened.
Check the hinges on the hard case. They should be strong and free of rust.
The handle should be firmly fixed to the main body of the briefcase by reinforced stitches or metal fixing devices. After a period of use, the handle attached to the outside of the bag may become loose.
The edge of the case is the point where the leather is most likely to peel or split.
