The designer said in an interview: "Screws are one of the tools I use a lot. I often think about the existence value of screws. It is mass-produced. People use it and discard it at will. They are so inconspicuous. Screws It is the unsung hero of the tool world. So I suddenly got the inspiration for this creation, giving the screws a face and expression." He also said: "Smiley screws not only have the function of ordinary screws, but also make people happy." He developed this smiley screw with a furniture company that produces more than a million screws a month. It is reported that the top of the ordinary screw is produced by the mold, but the smiley screws need to be carved one by one. Accurately grasping the expression on the screw cap, especially the depth and width of the eye groove, is very difficult to grasp. Currently, he only made some smiley screws as models, but also plans to make more smiley screws as art decorations until mass production. According to the British "Connected" magazine reported on March 31, a Japanese designer named Yuma Kano designed a smiley screw, the concave part of the nail is a smiley shape, which can be easily used with a matching screwdriver. The invention makes the upper screw also fun and interesting. 5'' Led Working Light,Led Auto Interior,Led Interior Lights,Led Auto Interior Lights CHANGZHOU CLD AUTO ELECTRICAL CO.,LTD , https://www.cld-led.com
