Abstract: An anti-theft tag includes a body that carries an EAS sensor, a shrinkable sleeve disposed about the outside of the body, an adhesive material disposed on the body between the body and the sleeve, and a sleeve holder extending from the body. The sleeve holder is constructed and arranged to hold the sleeve on the body such that a portion of the sleeve and the body define an aperture configured to receive an elongate article, such as an arm from a pair of eyeglasses.
