1. Mega Twister seals are etched with permanent laser marking. Laser marking offers the highest level of security as it cannot be removed and replaced.

2. The side flap area is etched with sequential numbering, logo or other customised marking for high security and easy identification.

3. Colour coding is possible with different combinations of the Mega Twister’s clear transparent body and its twister caps, which come in a variety of colours.

4. Heat staking is used to permanently affix the twister inside the seal’s body. If the seal is cut or forced open, this ensures it leaves clear evidence of tampering.
