Uni-ball Pin Ultra Fine Brush Tip Fineliner Drawing Pen Black Box of 12

uni-ball's model page calls the nib ultra fine and its 2026 catalogue calls it extra fine. The price list code ends in EF. We use ultra fine, as the model page does, and state both.

uni-ball publishes no numeric width for either brush nib, so we state none.

uni-ball's model page describes the ink as waterproof and fade proof. We hold no test result of our own, so we repeat uni-ball's wording and add nothing.

uni-ball's model pages say waterproof, fade proof ink and name no ink type. Its 2026 catalogue calls the ink pigment ink. We state both, make no lightfastness claim, and uni-ball publishes no archival or acid-free statement for the Pin, so we make none.

uni-ball publishes no calligraphy nib or calligraphy use for the Pin, so we do not call it a calligraphy pen. It also publishes no technical drawing use for the Pin, so we do not call it a technical drawing pen.

uni-ball lists one for the Pin ink, titled 'INK for uni PIN②' and dated 27 May 2025. It states the ink is not classified as hazardous and a signal word is not required. We make no other safety claim and make no non-toxic claim.

uni-ball and Mitsubishi Pencil Australia publish no country of origin for the Pin, so we state none.
