Uni-ball Signo Broad UM-153M Gel Ink Rollerball Pen 1.0mm Metallic Assorted Box of 12

uni-ball and the MPA price list publish no colour list and no count per colour for the assorted box, and we do not guess.

uni-ball's 2026 catalogue lists a 1.0mm tip for the Broad pens, UM-153 and UM-153M.

The only uni-ball page for the metallic Broad ink is the one for its five piece wallet, which calls it waterproof pigment ink. This box has no page, so we do not apply that wording to it and make no claim about water, fade or time.

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

uni-ball's catalogue entry does not make this clear for the Broad pens, so we do not state it either way.

The MPA price list sells this code as an assorted box of 12. The barcode on this listing is the one on the box, and the MPA price list gives no separate single pen barcode.

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.
