Smooth writing experience
I use these for grading papers and taking notes. The gel ink glides across the paper without skipping. Having red, black, and blue in one convenient press-type format saves so much space in my pencil case.

Perfect for my delivery route
As a courier, I need pens that write clearly on various surfaces and don't smudge. These Aihao 505 pens are fantastic. The thick refill lays down a bold line that is easy to read, and the press mechanism works smoothly even after weeks of heavy use.

Good student pen
My son uses these for his engineering diagrams. The thick line helps visibility, and the retractable design means he doesn't lose caps. They last a long time too.

Reliable and bold
The 1.0mm tip is exactly what I was looking for. It writes dark and thick, making it great for filling out forms or labeling boxes. The grip is comfortable for long writing sessions.

Excellent multi-color option
Love the convenience of switching colors instantly. The ink dries quickly and doesn't bleed through standard printer paper. Highly recommend for anyone who color-codes their notes.

Great value for office bulk buying
Bought a box for our warehouse team. The ink flows very well and the colors are vibrant. The only reason I didn't give 5 stars is that the clip feels slightly flimsy, but for the price, you really can't beat the quality.
Q: Does the ink work well on glossy shipping labels?
A: The oil-based gel ink is formulated to adhere well to semi-gloss and matte surfaces, making it suitable for most standard courier shipping labels.
Q: Are the refills replaceable when the ink runs out?
A: Yes, the Aihao 505 features a standard thick refill design that can be replaced once the ink is depleted, extending the life of the pen body.
Q: Is the grip soft or hard plastic?
A: The pen features a textured soft-grip section near the tip to provide comfort during extended writing periods.
Q: Can I buy just the black version separately?
A: This specific listing is for the multi-color set. However, single-color packs are often available in our store under different SKU listings.
Q: What is the approximate ink capacity per color?
A: Each color chamber holds approximately 1.2ml of ink, which typically lasts for several thousand meters of continuous writing depending on pressure applied.
