Today I received, a Interesting Feedback from one of the users from the US.
He tried to fit the Custom barrel and Cap to Platinum President.
The Barrel and Cap is actually for Platinum Century #3776.
He's Photography is Excellent, he's pretty pro at it (much better than me)
I am not 100% sure, but he also seems to make the pen rests, they look really cool.
Please Check his instagram out!
It's such a beautiful pen, and the pen rests look really cool!
