The top ultimate version of the spot is issued in seconds. Today, I will explain this classic first, ZP anti-counterfeiting label to the treasures. This ZP has 3 sets of anti-counterfeiting labels. The first set is on the edge of the last button of the adjusting ring. The material, year and place of origin of the product are engraved on this edge, and there is also a number printed with a steel seal. This steel seal is much more difficult than the little red man’s charity, because its stress area is too small, only a little bit as small as the edge. It is absolutely not easy to manually print a steel seal smaller than the edge.
