Rollerball/Felt Tip Cartridge Grip Sections for "Full Sized" Pens

$28 ~~$40~~ In stock

Our Rollerball/Felt Tip replacement grip sections allow you to convert your Schon DSGN "Full Sized" fountain or roller ball pen to accept two fun and unique refill cartridges from Schmidt!

The first is the Safety ceramic roller, a silky smooth writer with proprietary tech to keep it from drying out even when uncapped for extended periods.

The second is the FineLiner, a spring-backed felt tip cartridge with a super unique feel that offers a fine lined, marker like writing experience.

Both refills are included with the grip section, which is available in both natural and black ultem.

These grip sections can only be used with our engineered plastics and anodized aluminum "Full Sized" fountain pens, and are not compatible with any of our pocket fountain pens or classic and V2 ballpoint pens.

The threading is machined perfectly, so swapping between the rollerball and felt tip refills takes seconds with zero wobble. My full-sized pen feels completely solid with the Schmidt cartridges seated in there — no leaks after a week of daily use.

Been using this to swap between rollerball and felt tip on the fly, and the threading is buttery smooth every time. The grip section feels solid in hand and the Schmidt cartridges click in without any fuss. Honestly, it's turned my everyday pen into two different writing experiences for the price of

The swap to Schmidt refills took me all of two minutes, and now my favorite pen has that smooth rollerball glide I've been chasing. The grip section threads on perfectly with no wobble, which is exactly what I hoped for.
