These clear dome style ink tags are filled with a bright pink/red dye. They are very visual and deter shoplifters effectively. These must be used with a backer tag. You may use a sensor tag for double protection or use a clutch type backer for use without a security system. Purchase bubble clutch backers for use with a magnetic detacher, or purchase the gray clutch for use with Sensormatic detachers. Case pack is 500 tags.
