Have a question about a supposedly Korean product

dashcloud thought this was worth mentioning said

Hi, for some time now I've had a box of Lotte Pepero, which is described as "White cookie- harmony of crunchy cookies and white chocolate".
That's all fine, but the box also proudly proclaims "Korea No. 1 Brand". Is this merely a marketing gimmick, or is the product actually a top-rated/selling product?

For all the non-Korean Meh folk: what #1 products have you had that aren't from your native country?
