Fineline

Fineline is a United States-based provider associated with Fineline Applicators, a line of precision dispensing tools designed to deliver reliable, ready-to-use application solutions. Based in Fayetteville, the company emphasizes applicators that feature an air-tight, cap wire closure system intended to keep liquids ready for immediate use and protected from degradation. This design focus supports consistent performance across a range of mediums and viscosities.

The Fineline Applicator typically includes an 18 gauge (.8 mm) stainless steel dispensing tip or a 20 gauge (.5 mm) stainless-steel dispensing tip, paired with a 1.25-ounce low-density polypropylene bottle equipped with an 18/410 threaded neck. A notable aspect of these products is their compatibility with a broad selection of dispensing tips, enabling easy customization for different liquids and applications. Four bottle cap sizes are available (15/410, 18/410, 20/410, and 24/410), allowing the system to work with existing bottle formats and further enhancing adaptability for various projects.

End users can employ Fineline applicators with a wide array of materials, including acrylics, inks, gutta, masking fluids, watercolors, oil paints, silk dyes, stains, henna, water-based glues, and glazes. The design features a long stainless steel needle intended to provide precise placement and a free-flow, non-clogging operation. After use, the cap wire can be slid into the needle and secured, and removal involves twisting and pulling upward in stages to minimize waste and maintain bottle integrity.

A core selling point of the Fineline system is its versatility and user-friendliness. The available needle sizes include 16 gauge (1 mm), 18 gauge (.8 mm), and 20 gauge (.5 mm), with options to purchase a three-bottle kit. The product is marketed as simple to use, non-clogging, and reusable, with an oval bottle designed to aid handling and control during application. The overall concept centers on reliability and precision for artists and professionals working with delicate lines, dots, and continuous designs on materials such as paper, canvas, glass, ceramics, wood, metal, and fabric.

Beyond basic dispensing, the Fineline line is described as adaptable for drawing activities, enabling free-hand designs, precise spots, and continuous lines. The system supports varied viscosities through multiple dispensing tip options and emphasizes air-tight performance to prevent drying and degradation—an important feature when working with fast-drying liquids like acrylics. The combination of interchangeability, durability, and a compact bottle format positions Fineline as a flexible toolset for craft, art, and small-format labeling or detailing tasks.
