Does the pen come with ink?

No. The listing states ink is not included, so you need to buy pigment ink separately before first use.

What tip size is this pen?

The listing describes a 0.1 mm / 0.5 mm stainless steel tip, and the size is marked on the pen and cap. Confirm the exact size with the seller before ordering.

Is it good for beginners?

It works for anyone drawing on tracing paper, but pigment ink clogs if neglected. Expect to flush the pen regularly.

How does it compare with disposable technical pens?

It costs more up front but refills and lasts longer. Disposables need no cleaning but cannot be refilled.

How should I clean it?

Disassemble the pen and flush the tip and reservoir with water, then let it dry fully before refilling.
