Blåhaj is popular in some countries. Blåhaj shopping bags are sold in Taiwan and Malaysia. Blåhaj has also been used in advertisements, such as for tiny apartments in Japan (as a real estate agent) and Hong Kong's Tsim Sha Tsui branch, which was nicknamed "Tsim Shark Tsui". Colored Blåhaj-shaped red bean and sesame filled buns were sold for a limited time in Malaysia and Taiwan respectively.
