*This feed was developed about a couple of weeks ago,

so all the shipped pens recently are equipped with this feed.

upgraded features of the 4G v3:

- more slanted cut towards the front

- air channel modded for maximum flow while achieving high stability

- ink channel and air channel machined deeper

- frontal area higher precision, allowing perfect horizontal balance of the nib

- better compatibility with eureka nibs (overall nib groove shape)
