Achieving stable eyelash extension placement depends heavily on matching the fan base to your specific application technique. While exact numeric base widths may not always be listed in product data, starting with a narrow premade volume fan format provides a controlled, cohesive anchor point for natural lashes.
The width of a premade lash fan base directly governs its contact zone on the natural eyelash. A properly fitted base ensures reliable adhesive adhesion without placing uneven stress on the natural lash. Because numeric measurements for base width are rarely stated in standard product documentation, professional evaluation through practical sampling is the best way to verify compatibility.
This narrow volume fan collection offers extensive configuration versatility. Fan sizes range from 6D, 8D, 10D, 12D up to 20D fan formats, supporting customized volume intensity. Available curl profiles include J, B, C, CC, D, DD, L, L+, M, LC, and LU, paired with lengths spanning from 6 mm to 18 mm (as well as mixed-length trays).

Fibers are crafted from premium materials such as Korean PBT, silk, and luxury cashmere. Available thickness variations (0.03 mm, 0.05 mm, 0.07 mm) allow lash stylists to fine-tune retention and weight distribution for every application.
Prior to bulk purchasing, testing small samples helps evaluate base wrap, contact uniformity, and glue pickup. UBEMAY implements rigorous multi-stage quality control—including incoming material checks, functional performance evaluations, finished goods inspection, and final pre-shipment verification. Verified quality concerns are backed by product replacements, technical guidance, and full OEM/ODM manufacturing assistance.
These lash systems serve high-end salons, independent studios, and lash academies. For instance, a recent wholesale project involved supplying an eyelash distributor in Brazil, focusing on diverse fan styles, reliable quality standards, and structured international shipping logistics.
| Factor | Available Specs | Application Strategy |
|---|---|---|
| Fan Format | Narrow premade volume fan design | Test sample bases to confirm physical contact area and attachment stability. |
| Fiber Thickness | 0.03 mm, 0.05 mm, 0.07 mm | Select diameter based on client natural lash capacity and desired fan volume. |
| Fan Volume | 6D to 20D options | Balance fan density against weight and base attachment space. |
| Curl Profile | J, B, C, CC, D, DD, L, L+, M, LC, LU | Choose curls that blend naturally with the natural lash growth direction. |
| Lash Length | 6–18 mm & mixed options | Verify length balance to maintain secure base adhesion near the root. |
| Base Width Spec | Verified via sample testing | Perform live sample trial before committing to large-scale private label orders. |
Is there a specific base width measurement provided for these fans?
Numeric base dimensions are not explicitly listed in standard product sheets. Physical sampling is recommended to directly assess base contact surface and placement fit.
What parameters should be evaluated during sample testing?
Evaluate the narrow base structure, attachment zone stability, fan symmetry, fiber material quality (Korean PBT, silk, cashmere), thickness (0.03–0.07 mm), curls (J through LU), and length options (6–18 mm).
Are OEM/ODM and customized order options available?
Yes. Sample orders start at 1 unit, while custom branding orders begin at 100 units. Custom manufacturing standard turnaround is approximately 15–30 days with complete OEM/ODM support.
Opting for a narrow premade fan structure offers ideal control for lash technicians seeking secure placement. Because exact base measurements require hands-on verification, conducting a preliminary sample trial is highly recommended.
