Robert of TwoFish has made clever things since 1993, always in the U.S., and it's been a good life. They work as intended and come in handy for other things, which you can discover yourself. The entire country of Japan is nuts over the flashlight holder-if I told you how many they bought a year you'd think I was lying. The actual figure is confidential.
