How to Check if Premade Lash Fans Open Evenly and Cleanly

Evaluating premade fan bases requires more than checking a single lash. Examine several fans from different rows and confirm that they open evenly, maintain aligned fibers, and have stable, undistorted bases. Samples should also match the ordered material, thickness, curl, length, and narrow-fan configuration.

Practical Inspection Checklist

• Review multiple fans for uniform opening, straight lash fibers, and consistent base construction.
• Verify the sample specifications, including Korean PBT fiber, silk, or cashmere; 0.03, 0.05, or 0.07 mm thickness; and 6–18 mm or mixed lengths.
• Compare several configurations, such as 6D, 8D, 10D, 12D, and 20D, because one excellent fan cannot represent an entire tray.
• Choose samples that perform consistently with the application methods and working kits used by salons, training academies, and independent lash artists.

What a Clean-Opening Fan Should Look Like

A well-made premade fan should display a balanced spread with no obvious twisting, clumping, or deformation at the base. Both the fan design and the stated product specifications need to be assessed together. This range is described as narrow premade volume fans in 6D, 8D, 10D, and 20D options, while 12D is also referenced in the product name. The physical sample must correspond to the configuration selected for purchase.

Inspect fans from more than one row and avoid selecting only the most attractive piece. Check whether the bases retain a similar shape and whether the fibers separate at comparable angles and spacing. Consistent performance throughout the sample offers stronger evidence of manufacturing quality than a single fan that opens well.

Confirm the Product Specifications

Record the material and dimensions during the inspection. Available materials include Korean PBT fiber, silk, and cashmere. Curl choices include J, B, C, CC, D, DD, L, L+, M, LC, and LU. Thickness options are 0.03, 0.05, and 0.07 mm, with lengths available from 6–18 mm or in mixed sets. These details should match the approved sample and the intended lash extension technique.

Supplier and Quality Review

UBEMAY lists incoming inspection, functional testing, finished-product inspection, and pre-shipment inspection for this product. These procedures provide useful information when reviewing a supplier, but a buyer should still request and evaluate a physical sample before approving a larger order. The stated minimum order quantity is 1 piece for sampling, while custom orders begin at 100 pieces.

Reported cooperation includes a wholesale eyelash extension project for a Brazilian distributor involving fan lashes and accessories, along with a complete lash product sourcing project for a professional distributor in Italy. These examples show experience with distribution and sourcing support, but they should not be treated as independent proof of clean-opening performance.

The product lists an FDA credential for eyelash extensions in the United States. UBEMAY 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 relate to the specified products and do not automatically verify the opening consistency of premade fans.

Frequently Asked Questions

How should I test a premade fan sample?

Inspect multiple fans from different rows and compare their base shape, fiber direction, spacing, opening pattern, and specifications. A single successful fan is not enough to approve a tray.

Which details must match before evaluation?

Confirm the fiber material, curl, thickness, length, and fan volume. The listed choices include Korean PBT fiber, silk, and cashmere; 0.03–0.07 mm thickness; 6–18 mm or mixed lengths; and several curl and fan-count options.

Is a sample available before placing a custom order?

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

Conclusion

Approve premade fan bases only after several sample fans demonstrate even opening, aligned fibers, stable bases, and consistency with the requested product specifications.
