Smooth and reliable

No skipping or blobbing. I use these for architectural sketches and the precision is outstanding. The water-based ink is easy on the nibs too.

Best pen for manga inking

I have tried many technical pens, but the Mihoshi series is my favorite. The line consistency is perfect for drawing hair and eyes in manga. Truly waterproof once dry.

Perfect for Gundam detailing

These pens are incredible for adding fine panel lines to my Gundam models. The ink flows smoothly without bleeding, and it dries instantly. Highly recommended for modelers.

Good for beginners and pros

Very forgiving for beginners but precise enough for professionals. I deducted one star because the finest tip requires a very light hand to avoid breaking.

Great quality, slightly pricey

The quality is undeniable. The tip is very durable and doesn't fray easily. My only complaint is the price compared to local brands, but you get what you pay for.

Authentic Japanese quality

As expected from a Japanese brand, the engineering is top-notch. The cap seals tightly so the pen doesn't dry out even if left open for a few minutes.

5 FAQ

Q: Does this come in a set or only individually?

A: This specific listing is for a single piece. However, we also offer multi-piece sets with various line widths in our store catalog.

Q: What is the difference between this and a standard felt-tip marker?

A: Technical pens have a rigid metal tube tip that provides consistent line width regardless of pressure, whereas felt tips vary in width based on how hard you press.

Q: Is this pen safe to use on plastic model kits like Gunpla?

A: Yes, the water-based pigment ink is safe for plastic surfaces and will not dissolve or damage the plastic material of Gundam models.

Q: Can I refill this pen with other brands of ink?

A: We recommend using only original Uchida Mihoshi refills to maintain optimal flow and prevent clogging. Using other inks may void the warranty.

Q: How do I clean the tip if it gets clogged?

A: Simply wipe the tip gently with a soft cloth dampened with water. For stubborn dried ink, soak the tip in warm water for a few minutes before wiping.
