Where blacklighting is not the end all be all in detecting fakes, it is a tool that can be used. Along with your knowledge of a piece, it may help you determine an authentic item from a fake. It works on cloth items and paper. If an item glows (or would fluoresce) under the blacklight, it may mean you want to research it further prior to purchase. This is a handy compact item that you can take to shows with you.
It measures approximately 3 1/2" long and is silver in color. It takes 3 AAA batteries (not included). The on/off switch is on the end cap. Comes with wrist lanyard.
