Great value student pen

Solid build quality for the price. The grip is comfortable for long writing sessions. I deducted one star because the included ink cartridges run out slightly faster than expected.

Perfect for daily note-taking

The 0.38mm nib is incredibly smooth and precise. It glides over paper without skipping, making it ideal for my university lectures. The erasable feature is a lifesaver for quick corrections.

Reliable and refillable

Love that this uses standard international cartridges. It's eco-friendly to just replace the ink rather than the whole pen. The erasable ink disappears completely when rubbed.

Smooth writer, stylish design

The 'Time Capsule' design looks vintage yet modern. Ink flow is consistent, and I haven't experienced any drying issues even after leaving the cap off for a minute accidentally.

Excellent for calligraphy practice

I bought this for my daughter to practice handwriting. The fine tip helps her form letters neatly, and the fact that mistakes can be erased cleanly is fantastic for beginners.

Good but nib is very fine

The pen writes well, but the 0.38mm is finer than I anticipated. If you have heavy hand pressure, it might feel a bit scratchy on rougher paper. Works best on smooth notebook paper.
