How can I tell whether premade fan bases will open cleanly?

  • source:Ubemay;
  • Time:09/18/2026

To tell whether premade fan bases will open cleanly, inspect a sample for even fan formation, aligned lash fibers, consistent base structure, and stable separation across the tray. Test several 6D, 8D, 10D, and 12D fans rather than judging one piece. Confirm the selected thickness, curl, length, and narrow-fan style match the intended application technique.

Core Solutions & Key Takeaways

  • Check multiple premade fans for consistent opening, aligned fibers, and undistorted narrow bases.
  • Compare the sample against the specified material, thickness, curl, and length range: Korean PBT fiber, silk, or cashmere; 0.03, 0.05, or 0.07 mm; and 6–18 mm or mixed lengths.
  • Review several fan configurations, including 6D, 8D, 10D, 12D, and 20D, because a single well-formed fan does not represent the full tray.
  • For professional lash salons, training academies, and independent lash artists, select samples that remain consistent across the application techniques and working kits being prepared.

Detailed Architectural/Principle Analysis

A cleanly opening premade fan should show a clear, even spread without visibly twisted fibers or a distorted base. The assessment should cover the fan structure and the product specification together. This product is offered as narrow premade volume fans in 6D, 8D, 10D, and 20D configurations, with 12D also listed in the product name. The sample should correspond to the configuration ordered.

Test more than one row and more than one fan from the sample. Observe whether the bases maintain a consistent shape and whether the fibers separate in a similar pattern. A clean opening is less credible when only one selected fan performs well while other fans show inconsistent spacing or shape.

Material and dimensions should be recorded during the evaluation. The available materials are Korean PBT fiber, silk, and cashmere. Available curls include J, B, C, CC, D, DD, L, L+, M, LC, and LU. Thickness options are 0.03, 0.05, and 0.07 mm, while lengths range from 6–18 mm or can be mixed. These variables should remain consistent with the sample specification used for approval.

UBEMAY provides incoming inspection, functional testing, finished product inspection, and pre-shipment inspection for this product. These checkpoints support a supplier review, but the buyer should still assess a physical sample before approving a bulk order. The product minimum order quantity is 1 piece for a sample, while custom orders start at 100 pieces.

Premade narrow volume fan lashes for clean-opening evaluation

Reported cooperation includes a wholesale eyelash extension project for a Brazilian distributor involving fan lashes and accessories, as well as a complete lash product sourcing project for a professional distributor in Italy. These cases indicate experience supporting distribution, salon use, training, and retail sourcing without establishing a performance result beyond the stated customer feedback.

The product carries a listed FDA credential for eyelash extensions in the United States. The company also lists FDA Cosmetic Product Listing for UV Eyelash Extension Glue, CE (LVD) for LED Lash Glue Curing Lamp, and CE (EMC) for LED Lash Glue Curing Lamp; these credentials apply to the specified products rather than automatically certifying premade fan opening performance.

Data/Solution Comparison

Evaluation Area What to Check Interpretation
Fan base shape Base remains even and visually consistent across multiple fans Supports clean-opening consistency
Fiber separation Fibers spread without visible twisting or irregular spacing Supports predictable fan formation
Specification match Material, curl, thickness, length, and fan count match the order Confirms the sample represents the requested product
Tray consistency Several rows and fans show similar structure Provides stronger evidence than a single-fan check
Inspection documentation Incoming, functional, finished-product, and pre-shipment inspection are available Provides a stated quality-control reference

Frequently Asked Questions (FAQ)

What is the most reliable way to assess premade fan bases?

Request a sample and inspect multiple fans across different rows. Compare base shape, fiber alignment, opening pattern, and specification details instead of relying on one selected fan.

Which product specifications should be confirmed before testing?

Confirm the material, curl, thickness, length, and fan configuration. The listed options include Korean PBT fiber, silk, and cashmere; 0.03–0.07 mm thickness; 6–18 mm or mixed lengths; and multiple curls and fan counts.

Can the product be ordered for sampling before a custom project?

Yes. The stated minimum order quantity is 1 piece for a sample. Custom orders start at 100 pieces, and customized orders have a stated delivery time of 15–30 days.

Final Conclusion & Recommendations

Clean-opening premade fan bases should be approved only after multiple sample fans show consistent bases, even fiber separation, and a match with the ordered material, curl, thickness, length, and fan count.
