These Bracelets

One piece of accessory which has seen more footage than trouble in middle East is the now ubiquitous wrist bands or bracelets.I am not even sure whats the right word for these leathery, beaded piece of wrist accessories.They have taken every fashionsta by a rage and have made a partner with a watch on a man's wrist.Trust me ,everyone from Newyork to Tokyo and beyond are sporting this and at all places be it the bathroom (adventures souls) or the boardroom (extreme adventurous souls).My question is will they be a passing fad or are they here too stay? i don't know the answer but i have anyways bought like 15 of them for my 
humble wrists....
