I have been using these markers for over 30 years. They perfectly suit my special needs. The supplier that I had been using for many years, closed down due to COVID. I was very pleased when I found a new supplier and was very satisfied with the service that I received.

I work in a medical setting and love these pens for a few reasons - bought one years ago and tried to find them recently but no one carries them locally. The shipping from business was super fast and customer service was amazing
