Your favourite KOPI and TEH (that's coffee and tea in Singapore) are now on stickers!
Each sticker contains a drink at the bottom (e.g. KOPI O), which is described by a shorthand notation in the middle (e.g. KO).

Note for locals:
Send sticker to your friend who is buying.
Note for tourists:
Local coffee chains (e.g. Yakun, Toast Box) do not recognise the notations; it is only a concept. However, they do recognise the drinks at the bottom so I suppose you could show these stickers to get a customised flavour of your local coffee or tea.
