Uni-ball Deluxe UB-155 Liquid Ink Rollerball Pen 0.5mm Blue Box of 12

uni-ball's page lists a 0.7mm tip for the UB-177, a different code on the same page, and no tip size for the UB155. The 0.5mm figure comes from the Mitsubishi Pencil Australia price list.

uni-ball's own site names the UB155 on its Deluxe page and does not list it under Eye, so we call it by uni-ball's name.

uni-ball's 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 we hold no test result for this model.

uni-ball calls the ink liquid ink and does not classify it further for this model, so we do not call it pigment or dye.

uni-ball does not say for the UB-155, so we do not state it either way.

uni-ball publishes no refill for the UB-155, so we do not state one.

We found none naming the UB-155 among the 21 sheets on uni-ball's site on 8 October 2026, so we state no hazard classification. If you need one, ask us and we will request it from the supplier.

We list blue and red in boxes of 12. uni-ball's page names no colours, so these are Mega's own product colours, per the MPA price list.
