There have been horror stories of piranhas eating up any human unfortunate enough to wade into its territory, devouring everything in its path with surprising speed and efficiency. Thankfully, these are plastic piranhas that you see on the left, known as Kai Dental Floss Holder. As its name suggests, stored within the bellies of these truly monstrous (in terms of reputation and not size) fish lie a roll of floss, the scourge of all foodstuff stuck in between your teeth after a hearty meal. The teeth on these plastic piranhas were not quite cut out to slice flesh like a hot knife through butter, but instead offers a convenient and cute method of dispensing your dental floss daily.
There are five colors to choose from currently - red, blue, green, turquoise, and orange. Each Kai Dental Floss Holder measures 4" x 3" x 2.5". Replacement floss rolls are sold separately, so you can pick one up for $15.95. Pretty pricey in my opinion, but if it helps get your kids (and you) in the mood for some flossing, it'd be well worth the price.
