How to Check if Premade Lash Fans Open Evenly and Cleanly

How to Evaluate Premade Fan Quality

A reliable assessment of premade fan bases requires more than checking a single lash. Examine several fans from different rows of the tray and look for an even spread, straight and aligned fibers, an undamaged narrow base, and consistent separation. Test the exact fan style and specifications intended for application, including 6D, 8D, 10D, 12D, or 20D configurations.

Inspection Checklist Before Approval

• Review multiple fans rather than selecting only one visually attractive piece.
• Confirm that each base is narrow, stable, and free from twisting or deformation.
• Check whether the fibers open with similar spacing and maintain an even fan shape.
• Match the sample with the requested material, curl, thickness, length, and fan count.
• Assess consistency across several tray rows to obtain a more dependable quality judgment.

Key Product Specifications to Verify

The opening performance should always be considered together with the ordered product specification. This narrow premade volume fan range is available in Korean PBT fiber, silk, and cashmere. Thickness choices include 0.03, 0.05, and 0.07 mm, while available lengths cover 6–18 mm or mixed-length arrangements.

Buyers can also select from J, B, C, CC, D, DD, L, L+, M, LC, and LU curls. Because the product information references 6D, 8D, 10D, 12D, and 20D options, the physical sample should be checked against the exact configuration listed on the purchase order. A sample that opens well but does not match the requested specifications cannot fully represent the intended bulk product.

Practical Tray Testing Method

Begin by choosing several fans from different positions instead of removing only the most accessible item. Observe whether the bases retain the same width and shape, then gently assess whether the fibers separate in a predictable pattern. Look for straight fibers, balanced spacing, and a clean opening without crossed, twisted, or compressed strands.

Repeat the inspection with the specific thickness, curl, length, and fan count required for the application. This is especially important for professional lash salons, training academies, independent lash artists, and distributors preparing application kits. Consistent results across the tray provide stronger evidence than the performance of one handpicked fan.

Quality Control and Sampling Considerations

UBEMAY lists incoming-material inspection, functional testing, finished-product inspection, and pre-shipment inspection for this product. These checkpoints offer useful information when reviewing a supplier, but a buyer should still request and evaluate a physical sample before confirming a larger purchase.

The stated minimum order quantity is 1 piece for sampling, while custom orders begin at 100 pieces. Customized orders have a listed delivery period of 15–30 days. Sampling allows buyers to verify tray consistency, fan structure, and specification accuracy before committing to a private-label or custom production run.

Supplier Experience and Certification Notes

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 demonstrate experience with distribution, salon supply, training-related products, and retail sourcing, but they should not be treated as independent proof of a specific fan-opening result.

The product information lists an FDA credential for eyelash extensions in the United States. Other listed credentials include FDA Cosmetic Product Listing for UV Eyelash Extension Glue, CE (LVD) certification for an LED Lash Glue Curing Lamp, and CE (EMC) certification for the same equipment. These credentials apply to the relevant products and do not automatically verify the opening consistency of premade fans.

Frequently Asked Questions

How many premade fans should be checked?

There is no substitute for inspecting multiple samples from different tray rows. Testing several fans gives a more realistic view of production consistency than judging one selected fan.

What makes a fan base suitable for clean opening?

The base should remain narrow, even, and undistorted. The fibers should be aligned and separate with balanced spacing, without obvious twisting, clumping, or irregular gaps.

Which details must be confirmed before placing an order?

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

Is a sample available before a custom order?

Yes. The stated sample MOQ is 1 piece, while custom orders start at 100 pieces. Customized production is listed with a delivery time of approximately 15–30 days.

Final Recommendation

Approve premade fan bases only after several fans demonstrate an even opening, aligned fibers, stable narrow bases, and consistent spacing across the tray. The sample must also correspond to the ordered material, curl, thickness, length, and fan count.
