Reliable for medical notes

I needed pens that wouldn't smear on prescription pads or patient charts. These Deli pens are excellent. The retractable mechanism is sturdy and saves time.

Solid everyday pen

Good quality plastic barrel and consistent ink flow. The blue shade is a true classic blue, not too light or too dark. Will buy again when this pack runs out.

Great value pack

You get a lot of pens for the price. They feel comfortable in the hand during long writing sessions. One pen had a slightly stiff clicker, but the rest were perfect.

Perfect for daily office work

These pens write smoothly right out of the box. The blue ink is vibrant and professional looking. I use them for all my reports and they never skip.

No more lost caps!

I love that these are retractable. I used to lose caps constantly with my old pens. The clip is strong enough to hold onto my shirt pocket securely.

Smooth drafting companion

As an architect, I do a lot of quick sketching and field notes. The oil-based ink flows consistently without blotching. Highly recommended for professionals.

5 FAQ

Q: Is the ink waterproof?

A: The ink is water-resistant to a degree, making it suitable for standard document handling, but it is not fully waterproof for submersion.

Q: Does the clip break easily?

A: The clip is made from durable plastic integrated into the cap design. While no plastic is unbreakable, it is built to withstand normal daily pocket carry.

Q: Can I refill these pens?

A: No, the Deli 6505 model is designed as a disposable unit and does not support refilling.

Q: What is the exact tip size?

A: These pens feature a 1.0 mm medium point tip, which provides a balance between line width and precision.

Q: Are these suitable for left-handed writers?

A: Yes, the oil-based ink dries quickly, which helps prevent smudging for left-handed users.
