After announcing the news of their upcoming comeback and revealing member�Krystal, Victoria, and Sulli's teaser photos,�f(x) has unveiled Luna and Amber's�teaser photos for 'Electric Shock'.

Although 'M! Countdown' aired previews of the last two members last night, the official teaser photos released are a bit different. Much like the previous members' teaser photos, Luna and Amber are also seen sporting the shocking blue colored contacts.
