Breath Palette is a line 31 uniquely-flavoured toothpastes and mouthwashes. And I am not joking when I say unique - pineapple, green tea, pumpkin - and curry?! You can buy flavours individually or in flavour kits.
I discovered these just prior to my Japan trip, and grabbed about fifteen flavours at Tokyu Hands while in Tokyo. I am a sucker for minimalist packaging and large numbers!
