When customers look for a wide marker barrel, they usually care about three things: whether the body is easy to refill, whether the structure is stable, and whether the finished marker can work well with different ink systems. This 30mm Empty Marker Barrel series is developed around those practical needs.
All models in this range use a 30mm flat nib for broad strokes and fast coverage. The barrel capacity is around 30ml, which is suitable for large writing areas and longer working time. These empty barrels can be used for acrylic ink, water-based ink and other matching paint marker formulas, depending on your filling solution.
This product line includes transparent standard versions, injection-molded versions, a black barrel option and a colorful series for retail-oriented marker programs. Buyers can choose the structure according to product positioning, refill habit and market preference.
Available Models: AP-Z1930 / AP-1930 / AP-W1930 / AP-WB1930 / AP-S1930
Available Models
AP-Z1930 is the standard transparent version with a head-open refill design. The front section can be opened for ink filling. This structure is simple and easy to understand, making it suitable for basic wide marker products.
AP-1930 is a transparent injection-molded version, also using a head-open refill structure. Compared with the ordinary version, it presents a more integrated molded appearance and is often chosen for cleaner retail presentation.
AP-W1930 is an injection-molded model with head and tail refill design. The barrel can be opened from the rear for ink filling, which is convenient for users who prefer not to open the head section during refilling.
AP-WB1930 is the barrel head & tail-refill version. Its overall structure is close to AP-W1930, but the black body gives the marker a stronger finished-product look. It is often selected for industrial-style marker lines or darker packaging concepts.
AP-S1930 is the colorful series available in 8 color options. This model can be opened from both the head and the tail, giving more flexibility during filling and assembly. It is suitable for product lines that need brighter visual presentation or easier color distinction.
Why this series works well for wide marker programs
A 30mm marker is different from ordinary slim markers. Buyers usually use this size for broad marking, large lettering or high-coverage paint work. That means the barrel has to stay balanced in the hand, the nib seat has to be stable, and the refill structure should make production easier.
This 30mm Empty Marker Barrel series is built around that logic. The wide flat nib supports heavy strokes, while the 30ml body gives enough filling space for practical use. The different opening structures also help importers and marker brands choose a design that fits their own assembly process.

Material and Structure
The barrel body is made with durable plastic material suitable for marker production. The nib section is fitted for a 30mm flat tip, helping the finished marker produce thick strokes and visible coverage.
Depending on the model, the refill opening is placed at the head, the tail, or both sides. This gives buyers more freedom when planning ink filling, final assembly and product positioning.
Notes for Filling and Use
For wide markers, stable filling and proper sealing matter more than appearance alone. During assembly, it is recommended to match the barrel with suitable ink viscosity and nib material. After filling, the cap and opening parts should be closed firmly to help maintain sealing performance.
For long-term storage, markers should be kept in a clean and dry place. If the marker is used repeatedly, checking the nib condition and refill parts will help extend service life.
