  • Ten ink colours in one retractable barrel
  • Lightweight 15 cm plastic body fits a pocket
  • Smooth oily ink suits notes, doodles and journaling
  • Push-button mechanism keeps the point protected

Everyday writing tool

The Ruth's sister ballpoint pen measures 15cm and uses a .5mm tip for fine lines. Its plastic barrel keeps the weight low so it slips into a pocket or pencil case without bulk. The push-button mechanism extends and retracts the tip with one hand. Ten assorted ink colours are supplied at random for variety.

Consistent ink flow

The oily ink formulation resists skipping during long note-taking sessions. A .5mm ball maintains a steady line width whether you are writing quickly or adding small details. Because the ink is not erasable, marks stay permanent on paper. The retractable design protects the tip when the pen is tossed into a bag.

Pocket-friendly construction

The all-plastic shell survives daily knocks without cracking. A slim 15cm profile fits standard pen loops and shirt pockets. Push-button operation means no cap to lose or misplace. Random colour assortment adds a playful touch for school, office or casual journaling use.

Questions about this item

How much power does the 0.5mm ballpoint draw when writing all day?

The pen uses no electricity; it runs on oily ink and a spring-loaded push mechanism, so there is no power draw, heat or noise.

What must I already own for the 15cm pen to work?

Only paper or another writable surface is needed; the pen is self-contained with its own ink supply and retractable tip.

Will the plastic barrel and push mechanism feel consistent alongside older metal pens I keep?

The lightweight plastic body and push-type retraction give a different balance and click action compared with heavier metal pens, but the 0.5mm tip writes smoothly on the same paper.
