I'm glad you are coming over to Singapore ^^ sad to say there aren't much or any kailu stuff in Singapore T^T

And you can consider going to Comics Connection which is almost available at any shopping mall(not really at the town/city area) and they do sell lots of anime stuff and of course, non-official kpop merchandise. It might be costly but you can try out This And That too, they sell kpop merchandise too ^^

Hope you would enjoy your stay in Singapore ^^

Yayyyyyyyy!!!!! In Singapore you can find kpop stuff all around, though they don't have exclusive kpop-only stores. Hmmm, if you have it in your itinery you can plan for Bugis Street (it's a youngsters' territory and tons of clothes, shoes and bags), there's sort of a Korean alley (but please don't have too high of an expectation really...) there on the second level. Otherwise, you can go to Comics Connections around Singapore (can google it on streetdirectory.com for outlet locations); they used to sell comics (like manga!!!) and their figurines only but few years back with the kpop wave they've expanded to sell kpop merchandise too (not official goods though). They are mostly SM-related, heaps of EXO stuff hahahahhaa. Hope this helps and enjoy your trip!!!!
