A pen includes: an ink reservoir configured to store an ink; and a pen tip section including an ink application part configured to apply the ink to an ink application object. The ink application part of the pen tip section includes: a rigid tip made of a rigid material and having a hemispherical outer surface, an inner surface facing toward the ink reservoir, and a penetration part penetrating from the inner surface side to the outer surface side of the rigid tip; and at least one foam body filled in the penetration part at least on the side of the penetration part close to the outer surface side of the rigid tip, and provided with at least one air bubble formed to communicate from the outer surface side of the foam body to the inner surface side of the foam body.

A nib for a calligraphic dip pen includes a first inner plate with a first inner plate point end, a second inner plate with a second inner plate point end, and a core with a core top end. The first inner plate and said second inner plate are affixed to the core top end. The first inner plate and the second inner plate are bent toward an axial line of the core such that the first inner plate point end and the second inner plate point end are in contact. The nib for a calligraphic dip pen further includes a spacer plate positioned against either the first inner plate or the second inner plate. The spacer plate includes a spacer plate point end positioned in contact with both the first inner plate and the second inner plate.

Angled fountain pens are provided. A pen includes: a shank; an ink tube; a connector connected to the ink tube and the shank; a feeder connected to the connector; and a nib connected to the feeder. A writing tip of the nib extends through a hole in the feeder. The writing tip is resiliently biased against the feeder and is selectively moveable between a first position in which ink flow between the writing tip and the feeder is prevented and a second position in which ink flow between the writing tip and the feeder is permitted.

The present invention provides an omnibearing writable fountain pen, comprising: a shaft component in which an ink reserve chamber is contained; a feed component arranged at the front end of the shaft component to deliver ink reserved in the ink reserve chamber; a nib component including two nibs, each nib having a middle slit, the two nibs being stacked with each other in such a manner that a horizontal gap is disposed between the two nibs so as to form a nib tip having at least four ink channels in a front end of the two nibs, wherein each ink channel is connected through the middle slit and the feed component to the ink reserve chamber, resulting in an advantageous characteristic that makes the omnibearing writable fountain pen of the present invention omnibearing writable.
