SKY IM-U580S is a folder type mobile released in 2009 under the name of color therapy through SK telecom. The role of SH.SON in this project was to redesign for female consumers aged 10 to 20 based on the hardware specifications of the pre-developed IM-U585S. She designed the IM-U580S with metallic silver point color on white pearl base color that is popular with women aged 10-20. In addition, she applied soft and delicate lace pattern to the back of the front cover, which gave a three-dimensional impression and differentiated feeling from the other product in market. The silver deco of the front cover is an iconic face of the IM-U580S and a functional LCD. It is designed with metallic post-processing on a transparent window, which helps user to check the contents without opening the mobile when the message arrives.
