Blue Gel Ink In A Retractable Pen

This is the blue ink version of the uni-ball Signo 307M UMN-307M, a retractable gel ink pen whose line width uni-ball does not publish.

uni-ball names the Signo 307 a Retractable Gel Ink Pen and describes 'Skip Free' technology for stable ink flow. Its page lists M and F variants, gives no tip size and does not say what the letters mean. The price list from Mitsubishi Pencil Australia gives this pen the same 0.7mm description as the UMN-307F, while Mega's earlier listing said 0.5mm, so we state no width. The page shows the uni Super Ink logo, and Mitsubishi Pencil Australia advises that pens carrying it are water, fade and time resistant.

Blue is the colour that tells an original from a black photocopy, which is why it turns up in contract signing, invoices and approvals. A retractable pen has no cap to lose. It is sold by the box of 12, so a department is stocked in one order.

The black and red inks in this model sit alongside it in gel pens. The rest of the uni-ball range is at uni-ball, other pen types at pens, and notebooks, pads and the rest of the desk at writing supplies.

FAQs

It is not published. uni-ball's product page gives no tip size. The Mitsubishi Pencil Australia price list describes the UMN-307M as 0.7mm, the same as the UMN-307F, and Mega's earlier listing said 0.5mm. Because they disagree, we state no width.
uni-ball's page lists both codes and does not say what the M and F mean or how they differ. We make no claim about the difference.
The uni-ball page for this model shows the uni Super Ink logo, and Mitsubishi Pencil Australia advises that pens carrying that logo are water, fade and time resistant. We do not describe the pen as waterproof or fade-proof, and uni-ball publishes no test result for this model.
Yes, by uni-ball's own name for it. The page calls the Signo 307 a Retractable Gel Ink Pen.
uni-ball describes it as newly developed technology that offers an even smoother writing experience, stable ink flow and a clear writing line. The page gives no technical detail beyond that, and we do not add any.
We do not state one. uni-ball's page gives no refill code. The Mitsubishi Pencil Australia price list lists a UMR-87 refill against the UMN-307 Fine in red and against the UMN-152 Fine in black and blue, and the tip size of this pen is unresolved.
A box holds 12 pens, per the Mitsubishi Pencil Australia price list.
Not one we can attach. uni-ball's safety data sheet page lists 21 documents and none is named for this model, so we do not state a hazard classification for it.
