Description

Technical Field

[0001] The utility model relates to the technical field of marker pens, in particular to a marker pen shell and a marker pen. Background Art

[0002] Markers, as a modern writing and drawing tool, have a technical background that can be traced back to the early 20th century. With the advancement of industrial technology and the development of color science, markers have gradually evolved from simple marking tools to an indispensable medium in the field of artistic creation and design. Markers use specially formulated inks, which are usually divided into two types: water-based and oil-based. The former is brightly colored and environmentally friendly, while the latter is favored for its rich colors and quick drying. The core advantages of markers are their convenience, bright color expression, and high controllability, which enable artists and designers to complete their works efficiently in a short time.

[0003] As an innovative member of the marker pen family, the double-headed marker pen has a technical background that combines the advantages of traditional markers with the essence of modern design. The double-headed design means that a pen has both thick and thin nibs, which greatly broadens the application scenarios and creative possibilities of markers. The thick nib is suitable for large-area coloring and quick expression, and can quickly spread colors and improve painting efficiency; while the thin nib is good at fine depiction and line outlines, making the details of the work more vivid and realistic. The technical realization of the double-headed marker pen is inseparable from the precise mold manufacturing and ink control technology, ensuring that the thick and thin nibs can maintain a consistent writing and painting experience when switching between them.
