Great value beginner pen

Solid build quality for the price. I like that it works with both cartridges and a converter. The transparent body lets me see exactly how much ink is left.

Smooth writing experience

I bought this for adult calligraphy practice. The iridium tip glides effortlessly over paper without scratching. Highly recommend for beginners.

Perfect for my daughter's handwriting practice

The ergonomic grip really helps my third-grader hold the pen correctly. The ink flow is smooth, and the EF nib is great for small handwriting exercises.

Durable and reliable

My son has dropped this pen several times, and it still writes perfectly. The opaque version looks very professional despite being a student-grade pen.

Excellent posture correction tool

As a teacher, I recommend these to students struggling with grip. The design naturally guides the fingers into the right position without feeling bulky.

Nice blue ink color

The included crystal blue cartridges are vibrant and dry relatively quickly. The only minor issue is the cap can be a bit tight initially, but it loosens up with use.
