Nichkhun and his fellow 2PM members recently filmed a CF for 'Look Optical', and it's just been announced that the so-called 'Nichkhun glasses' have sold more than 10,000 pairs in one month! The 'El Sid-EL4005' model sold more than 2,000 pairs alone on the day it was first introduced in a Shinchon store. 300 pairs were sold everyday after that, adding up to more than 10,000 pairs being sold overall. The 'Nichkhun glasses' are fairly cheap, selling at about $12.50 USD. His endorsement produced approximately $125,000 in revenue for the brand. 'Look Optical' opened its first store on March 2nd, and gained attention by choosing 2PM and T-ara to be its spokesmodels. Source: Newsen via Nate
