Product Identity

The Pentel R100-A Rolling Writer is a capped roller-ball pen supplied as a dozen. Its Cushion Ball Tip adjusts to the user's writing style for an outstanding experience. The durable 0.8mm conical tip produces clean lines at any angle without skipping or smearing. Smooth, expressive black ink suits everyday notes and general writing tasks.

Suitability & Limits

Students and office workers who want reliable, skip-free lines for high-volume note-taking will appreciate the consistent flow. Buyers who need refillable barrels to reduce waste should look elsewhere. Users seeking ultra-fine points for detailed technical drawing or compact planners will not find the medium width suitable. Left-handers requiring fast-drying ink to prevent smudging may prefer a different formulation.

Deciding Specification

The 0.8mm medium tip width is the single specification that decides whether this pen fits the task. It delivers a visible line weight ideal for standard handwriting and signatures. Anyone needing a finer stroke for dense annotations or a broader laydown for bold marking should choose a different tip size.

Questions about this item

Will the .8mm tip feel consistent on the recycled paper I already use?

The Cushion Ball Tip adjusts to writing pressure and the 0.8mm point lays down clean lines at any angle without skipping or smearing on typical office paper.

How can I verify the ink flow is smooth right after unboxing?

Make a few test strokes; the roller ball should glide with no skips and produce an even black line from the first mark.

Does the dozen pack include refills or do I buy them separately?

The box contains twelve capped pens with black ink and pocket clips; refills are not included and must be purchased separately.
