Essential for teachers

As a teacher, I grade papers all day. Being able to switch between red for corrections and black for comments instantly saves so much time. Highly recommend!

Great value, sturdy build

This pen feels solid in the hand. The click mechanism is satisfying and hasn't gotten stuck yet. I deducted one star only because the green ink is slightly lighter than the others.

Perfect for color-coding my notes

I love having four colors in one pen. The black and red are my go-to for studying, but having blue and green available is a huge plus. The ink flows smoothly without skipping.

Good pen, but cap can be loose

The writing experience is smooth and the 0.7mm tip is perfect for daily writing. However, the clip on the cap feels a bit flimsy and doesn't hold tightly to my pocket.

Smooth oil-based ink

The oil-based ink dries quickly and doesn't smear, which is great for lefties like me. The rubber grip makes long writing sessions comfortable.

Reliable multi-pen

I've bought several of these for the office. They are reliable and the colors are vibrant. It's nice not to carry a pouch full of single-color pens anymore.

5 FAQ

Q: Does the push button work for each color individually?

A: Yes, there is a sliding mechanism or individual buttons (depending on the specific sub-model) that allow you to extend one color at a time while keeping the others retracted.

Q: What are the exact four colors included?

A: This pen includes Black, Red, Blue, and Green ink cartridges pre-installed.

Q: Is the ink waterproof?

A: The oil-based ink is water-resistant to a degree, meaning it won't smear easily if lightly exposed to moisture, but it is not fully waterproof for submersion.

Q: Can I buy refills for this specific pen model?

A: Yes, Deli offers standard multi-pen refills that are compatible with this 4-color model. Please check our accessories section for part number D-REF-4C.

Q: Is this pen suitable for left-handed writers?

A: Absolutely. The oil-based ink dries quickly upon contact with paper, significantly reducing the chance of smearing for left-handed users.
