Since 1978, TAMPER GUARD has been the leading evidence tape among technicians and other crime-scene personnel. Officers have come to rely on its integrity for sealing evidence bags, boxes and other containers. When placed on a surface TAMPER GUARD forms a seal that is virtually impossible to violate. In addition, a red dye within the adhesive will appear if any solution is used to try to open the taped container. Consistently proven over years of crime scene use, TAMPER GUARD is the evidence tape that outperforms all others. ***Comes in 12 Roll Pack.
