Trodat PSI is the latest development in the PSI family. these
stamps are "green," but unlike the previous stamps we have taken a new
approach to "green". We call this the LEM process. What is LEM? Low
Emissions manufacturing. What is that in English - No Chemicals used to
finish products - No Effluent goes down the drain - Manufacturing
process uses less power than it takes to light 100 watt bulb for 60
minutes. Our PSI
brand of pre-inked stamps have long been known for their quality and
reliability. They have patented features, which make them work and feel
as good as they look.These pre-inked stamps have precision components
that make the PSI stamps easy to use. A quality product made to for last
years.
