Uni-ball Signo Broad Metallic UM-153M Gel Ink Rollerball Pen 1.0mm Assorted Wallet of 5

Blue, violet, pink and red, which uni-ball's page and its 2026 catalogue both name, plus a fifth that they disagree on: the page says metallic green and the catalogue says metallic bronze. We do not pick one until uni-ball confirms the contents.

uni-ball publishes 1.0mm for this wallet in its tip size field and its 2026 catalogue. The description on the page prints it as 1.0mmm, which we treat as a typo.

uni-ball's page for this wallet calls the ink waterproof pigment ink, which is uni-ball's own wording, and publishes no test standard or result behind it. We repeat it as published and make no further claim.

uni-ball's 2026 catalogue lists acid free ink in its entry for UM-153 and UM-153M, and we repeat it as published.

uni-ball's page and catalogue give no refill code for the Broad pens, so we do not state one.

Not one that names this code. None of the 21 safety data sheets on uni-ball's site (checked 8 October 2026) names UM-153 or UM-153M, so there is no classification or handling statement for us to pass on. We will not borrow a sheet from a neighbouring Signo code, because the ink is not the same ink.

No. The UM-153S Gel Impact is a different uni-ball model with its own page, so we do not apply its details to this wallet.
