The Extreme Flash Thumb Tip byAlan Wong contains a high capacity lithium rechargeable battery with super bright LED unit which gives you a burst of white light at the push of a button. A versatile invisible electronic flash unit that you will use. You can produce a flash from your empty hand by quickly touching and releasing the button, or pluck the light off your mobile phone with your empty hand and it will look as bright and exactly the same where it came from then put it back. Warning: It is hazardous to stare into the light at close range, as you will be staring directly into the naked super bright LED bulb without any protection like looking at the sun directly. Each unit contains ONE Extreme Flash Thumb Tip with PVC carry case. Note that our price includes shipping in the USA. 001CBMEXTREMEFLASHTIP
