The Tile Mate 8-Pack retails for US$43.58 (S$60) and delivery to Singapore is an addition US$5.01 (S$7). That works out to be about S$8.40 per Tile Mate. In Singapore, Courts is selling a single Tile Mate for S$29 with no option to buy it in a pack.
I have been using the original Keysmart since I got it back in March 2017. The idea of organized keys is not new, but KeySmart nailed the execution.
As I was impressed by it, I even bought Li Xiang a Black KeySmart after using mine for a month.
