According to F.B.I. statistics, handguns comprised 70.5 percent of all firearms used in murders and non-negligent manslaughters in 2009. But for the fashion-wise femme fatale for whom plugging a victim full of holes is too heavy-handed and, like, messy, why not twist them around one’s little finger instead? To aid and abet such mortal seductions, the Dutch jewelry designer Ted Noten has made a group of handgun-shaped compacts as part of a series he calls “Seven Necessities.” Each faux firearm is devoted to a different cosmetic giant, Dior and Chanel among them.
