I finally received a text response from Illuma and the lady asked if I was interested in Illuma products for my practice. I responded and stated that I have an Illumapro pen and was interested in purchasing replacement cartridges. I never heard from her again. So very frustrating!!!
It’s the only toner I use but I rotate the 1970 and the new formulation. 1970 smells like phenol and the other smells like vinegar. But both are truly amazing.
