Mount Blanc..leaking.

[2807]

I have the Mount Blanc classic black pen. It is the big one, I forget the name.
I have the broad blue ink refills in it.

They leak ! Everyday I go to use it, there is a small blob of ink at the tip, messes up my signing/usage. I have to clean it off everyday...

I went to Mount Blanc to get more refills, thinking I just had a bad set of two...

They did not believe me. Sold me a new pack of two....
They leak too.

The shop said "you should store the pen upside down"

Really? I missed that in their marketing.. "Our nice pens leak, store them upside down to minimize problems"

I pointed out to them that NONE of the pens in their shop were displayed upside down...

Anyone else have a leaking problem with ink in broad/blue ?

Thanks
