When do you need a refill for your gel pen?

Is your gel pen no longer writing, or is the ink getting lighter? Then it's time for a new refill. With the uni-ball UMR-10 refill, you don't have to buy a complete new pen straight away; you simply replace the inner mechanism. This is not only more economical, but also more sustainable than buying a new pen every time.

Specifically for uni-ball GEL IMPACT pens

This refill has been specially developed for the uni-ball GEL IMPACT and BROAD models UM 153S and UM 153C. You therefore cannot use this refill in other pen brands or pen models. Always check the model number of your pen before ordering, so you can be sure the refill will fit.

Red gel ink for clear markings

The red colour makes this refill ideal for corrections, markings or highlighting important text. Red gel ink stands out well against black text and is therefore popular with teachers, editors and anyone who needs to check or annotate documents.

Easily replacing your refill

Changing a gel pen refill is simple: unscrew the pen, remove the empty refill and insert the new UMR-10. Take care not to damage the refill while inserting it, and check that it sits firmly before reassembling the pen.
