The design of this series of buttons is very novel, and the patterns on one of the buttons cleverly use Chinese elements to design, and the contrasting color design makes the buttons more exquisite. The patterns on the buttons are very delicately engraved, and the lifelike prints engrave the designer’s ideas. Another black button is also very cleverly designed. The button has brown irregular stripes. This novel design method and contrasting color design make the button more perfect.
