A stationery project in October 2020 coincided with the National Day. I remembered that on June 25, 1950, the Korean War broke out and soon the Chinese People's Volunteers entered the Korean battlefield. After the middle of 1951, China and the Soviet Air Force MiG-15 successfully intercepted U.S. fighter planes many times, forming the famous "MiG Corridor" over the plain on the south bank of the Yalu River ". For this reason, the MiG 15 was used as the design prototype and creative inspiration, and this MiG 15 children's hand-cranked pencil sharpener was made.
