Jay Park has increased the sales of Levi's dENiZEN jeans ever since he started endorsing them.

dENiZEN is a sub brand that is rooted from Levi Strauss jeans. It's a new casual brand that just launched on the third. In Korea, they signed Jay Park to advertise the jeans. He finished shooting photos for the endorsement on the sixth, but his fans already figured out that he was endorsing this brand through his YouTube videos and photos of him wearing the jeans. Because they knew about the jeans before it was officially announced, they have already gone out to buy themselves a pair. Many fans were present at the opening and bought tons of things. The company had seven times the amount of regular sales after it was announced Jay had endorsed the jeans. It puzzles me as to why Olympic Stadium would turn Jay down to perform there because they say it will cause problems, yet this brand is clearly benefiting from Jay.
