Misuse of CTL analysis

We have noticed that some companies are unrightly using "CTL approved" and even calling their products ... CTL inks. This is completely misleading as we only test products but definitely do not produce tattoo inks. The tests for the mentioned inks are over 5 years old and definitely no longer valid. Look up the products in our database before you fall for such misleading adverts.
