Lately i have been vaping GGTB, and i have to say the GGTB and Penlope is beautiful couple.Here are some words from Imeo about the new Penelope: As I have said before, the air control will not change the total length guys. Now I have to say that it will not change the external look too.Also I added more features that you will see them when time comesI think GGTB/Penelope will really be a revitalization for the GGTB-tube. And this beauty of an all brass GGTB is waiting and waiting and waiting ...
