2fast2cool2 is an eBay trading name for japseye, normally for selling off there slightly damaged or bad fitting goods. I bought a k1 briefly from them and it came in a half ruined japseye box and the centre silencer had two dents in it. Still worked though and was up to he usual japspeed standards meaning it fitted like a glove to your foot, and sounded like a fart in a baked bean can . Good luck though and the k2 is no where near as loud, plus more importantly its Cheap!
