## Description

Product Description Convenient red and blue ballpoint pen and pencil. This multi-system pen features a solid, simple form body with 2 color permanent ballpoint pens and 0.5mm pencils. Set Contains: LAMY tri pen st black (2+1) multisystem pen

Review: Great scribe tool for my construction notebook. - I carry a calendar/project binder with me everyday and this is the pen I keep in the pen holder. It takes quite a beating in my work truck. After 8 months of use it has held up great. Pros: Stays clipped and also un-clips nicely from my floppy pen holder. Clip is thin, but has held up better than I expected and hasn't bent. Black paint(?) finish has held up great with no scratches or chips. Ink writes reliably even when it sits in a cold truck over night. Feels solid, balanced and not too heavy. Cons: Ink is a little "sticky" as with most Lamy inks (similar in my experience to fisher space pens). Eraser cap seems easy to lose (see Q's and A's), so I tightened mine up by pinching it just a touch to keep it snug. You can retract all the inks/pencil, but it doesn't "click" into those positions - this seems like an issue if you were going to carry it in a shirt pocket - I keep mine turned to the pencil when I'm not using it to avoid it slipping to one of the inks and writing on me or something else. Would I buy this again? Absolutely. It's tough, reliable, and looks great. Edit: I’ve carried this pen for over 18 months now. It has a little bit of wear at the edges of the metal, but no scratches through the paint anywhere. Ink replacements are easy to find. Clip is still holding strong, and I haven’t lost the eraser cap!
Review: The best - Best writing instrument I’ve ever owned.

### ⭐⭐⭐⭐⭐ The best
*by B***L on May 27, 2025*

Best writing instrument I’ve ever owned.

### ⭐⭐⭐⭐⭐ Excellent multi-pen
*by J***S on March 10, 2019*

Top of the line pen, construction is amazing and the feel of the pen is great. Well balanced in my hand, selecting the various options (blue, red, pencil) is simple and it writes great. Very handy to have multiple colors and a pencil all available from one pen. The eraser under the cap is easy to use and the pocket clip holds the pen tightly in either my notebook or my shirt pocket. Highly recommneded for anyone looking for a well-made multi pen.
