I'm sure most everybody would be familiar with the tambun biscuits-in-a-box as sold by Ghee Hiang, Him Heang and loads of other imitators. Nowadays, there are all sorts of flavours too ... original, coffee, durian, etc. In my opinion, the original is still the best.
Those were the days. The biscuits sold simply because of quality and nothing more. By the way, it's still possible to buy them that way.
