The shop is really swarmed! Everybody's buying like there's no tomorrow. Koi Kei dominated the whole Macau. Every few metres there is a Koi Kei shop. The price in Macau is the cheapest. If you buy from Hong Kong, the price can differ by as much as 40%. So if you are in Macau, buy more! You can sample all their products before you buy. So happy sampling n buying!
