The logo mark is designed with consideration given to the formative characteristics of the "Happy Wing.” Using the logo mark solely has the advantage of fewer spatial restrictions and better legibility, but it lacks the symbolism to be used as an identifier representing SK.
Therefore, in principle, when expressed in the media, the logo mark should be used in combination with the "Happy Wing" symbol mark for the effective delivery of the SK identifier.

The "Happy Wing" is the element that represents the SK identifier’s formative characteristics and symbolism the best. In order to avoid any image degradation from distortion, modification, and misuse of the identity, the regulations and principles associated with the application of the symbol mark must be adhered to.
The "Happy Wing" is the representation of two soaring wings with the motif of a communication satellite, kite, etc., symbolizing the advancement of energy, chemical and information communication businesses, the two growth axes of SK, and it is the face of SK embodying the enterprising spirit towards the global market and the will of "the pursuit of happiness.”
