Both the Reo Grand and the Nuppin are authentic
Button on the Reo works great
So this is my offer, The Reo Grand with Upgraded Sub Ohm connections and adjustable 510, a SS Nuppin, a extra soft "Italian" Bottle, a Black Copper Vein door, a Full Brass door, extra Brass, Aluminum and Black Buttons and to top it all off one of my Clear Caps for the Nuppin
So I need some more details on your box mod (maker and board) and is your Petri 24K authentic as well?
