I see that Private Reserve is under new ownership and have come out with a whole line of colors to celebrate their return.

I had also heard, in the past, that Private Reserve, like many Noodler inks, were not all that safe to use in some fountain pens because of the formulary. Particularly vintage and older pens. I personally don’t use either, although I did have a soft spot in my heart for the old Private Reserve Arabian Rose

The new company says it’s using the same formulas — which leads me to the question of whether these inks are indeed safe to use in all pens or whether the old proviso of “buyer beware” still applies.

Any thoughts?
