The SEED Radar Twist is a Japanese retractable eraser that brings a clever twist to a familiar stationery essential. Instead of a traditional paper sleeve, the eraser is housed in a transparent protective body and advanced by simply twisting the base. This keeps it clean and protected from dust, stains, and damage inside your pencil case, while the refillable design allows you to replace only the eraser when needed.
Available with square, triangular, or round erasers, Radar Twist lets you choose the shape that best matches your way of working. The square version offers crisp edges for highly precise corrections, the triangular shape combines a broad surface with a fine tip for versatility, while the round eraser is ideal for quickly clearing larger areas. Each shape is designed to make everyday corrections more controlled and intuitive.
Compact, durable, and thoughtfully engineered, SEED Radar Twist is an excellent choice for students, architects, designers, illustrators, and stationery enthusiasts alike. Combining SEED’s renowned erasing performance with a clean retractable mechanism and replaceable refills, Radar Twist turns a simple everyday tool into a more practical, portable, and long-lasting precision eraser.

I've tried almost all of the pocket fountain pens out there, especially the ones with a #6 nib, and this Quark is my favorite of the bunch.
The material choice in a stone wash finish is perfect for a pocket pen. It provides good texture to grip and handle the pen, which you will be doing a lot because you need to unscrew to uncap and then screw to post... and then again in reverse to put the pen away. But the zing! of the zirconium makes each writing opportunity such a pleasurable experience. You're able to do this quickly as well because of the minimal turns it takes manipulate the cap. The grooved texture of the grip is also excellent. Just enough to give you a good grip but never in your way. I do wish the grip section was about 1mm thicker though.
I have mine fitted with a Pilot #15 nib and eyedroppered. I smile every time I take it out of my pocket... the zing... the reveal of the 14k Pilot nib... the perfectly textured groove section. The whole package just comes together so lovely!
If I had to complain though, my one gripe is that when posted, the cap wiggles ever so slightly. It's very minor, but you do feel it move in your hand when writing from time to time. Also, mine takes about 1.5 rotations to uncap, but the description says 0.6 turns. On the plus side, it can post in 1.5 turns, even though the description says 2 turns. Not sure if this is just a variance in manufacturing.
But overall this is an amazing pen. I have been eyeing it for over a year and now I wish I had gotten it sooner.
