Lamy Studio: Simple Swap

[Chrissy]

Every time this thread pops up I want one of these pens. Because it comes with the same nib as the Safari and Al-Star etc but doesn't come with the tripod shaped section I imagine it is as comfortable to write with as the Lamy Nexx. One of my problems with the slightly rubberised Nexx section is that it won't go down far enough into Diamine 30ml ink bottles for filling. It also attracts dust/bits to that slightly rubberised surface.

I see that this section looks like it is made from harder plastic and wonder if that means it will fill from Diamine 30ml ink bottles? Does anyone who has a Studio know the answer?
