How to Evaluate Premade Lash Fans for a Clean Opening

Determining whether premade lash fans open cleanly requires more than inspecting one attractive piece. Select fans from different rows and check for an even spread, aligned fibers, a narrow and undamaged base, and consistent separation throughout the tray. The sample should also match the material, thickness, curl, length, and fan count required for the intended volume-lash technique.

What a Clean-Opening Premade Fan Looks Like

A well-formed premade fan should open into a balanced shape without visibly twisted, crossed, or uneven fibers. Its base should remain narrow, stable, and free from crushing or distortion. Similar spacing and separation from one fan to the next provide stronger evidence of quality than a single fan that happens to open well.

• Look for an even fan spread with fibers that remain aligned.
• Check that the base keeps a consistent, narrow shape instead of appearing flattened or misshapen.
• Compare several fans from different tray rows to identify irregular spacing or inconsistent opening.
• Confirm that the selected product suits the lash artist's working technique, kit configuration, and target volume effect.

Step-by-Step Sample Inspection

1. Examine fans from multiple areas of the tray

Take several fans from more than one row or section of the sample. Observe whether the fibers separate in a similar pattern and whether each base maintains the same general shape. A successful inspection should represent the tray as a whole, not just the easiest fan to select.

2. Compare the available fan counts

Where applicable, review 6D, 8D, 10D, 12D, and 20D fans. The product description identifies narrow premade volume fans in 6D, 8D, 10D, and 20D configurations, while 12D is also included in the product name. Because the listed configurations should correspond to the actual order, ask the supplier to clarify the exact fan count before approval.

3. Verify fiber and dimensional specifications

The sample must be evaluated against its stated specifications. Available materials include Korean PBT fiber, silk, and cashmere. Thickness options are 0.03, 0.05, and 0.07 mm. Available lengths range from 6–18 mm or may be supplied as mixed lengths. The curl selection includes J, B, C, CC, D, DD, L, L+, M, LC, and LU. Record these details during testing so the approved sample is directly comparable with the bulk order.

4. Check suitability for the intended application

Professional lash salons, training academies, and independent lash artists may prepare different working kits and use different volume techniques. A fan that opens consistently should also correspond to the selected thickness, curl, length range, and density required for the planned service. Consistency across the chosen specification is more useful than judging a different configuration that was not ordered.

Quality-Control and Ordering Considerations

UBEMAY lists incoming inspection, functional testing, finished-product inspection, and pre-shipment inspection for this product. These checkpoints provide a useful reference when reviewing the supplier's process, but they do not remove the need for a buyer to inspect a physical sample before approving a larger purchase.

The stated minimum order quantity is 1 piece for sampling, allowing buyers to review the fan structure before committing to production. Custom orders begin at 100 pieces, with a listed customized-order delivery period of 15–30 days. Confirm the final specification, packaging, quantity, and delivery schedule before placing a custom order.

Reported Projects and Listed Credentials

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 indicate experience supporting wholesale and distribution requirements, but they should not be treated as independent proof of a specific fan's opening performance beyond the stated customer feedback.

The company lists an FDA credential for eyelash extensions in the United States. It also lists 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 type of lamp. These credentials apply to the specified products and do not automatically certify the clean-opening performance of premade fans.

Frequently Asked Questions

What is the most dependable way to test premade fan bases?

Request a physical sample and inspect multiple fans from different tray rows. Review base shape, fiber alignment, opening pattern, tray consistency, and product specifications rather than relying on one selected fan.

Which specifications should be confirmed before testing?

Confirm the fiber material, curl, thickness, length, and fan configuration. 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.

Can I purchase a sample before starting a custom project?

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

Final Recommendation

Approve premade fan bases only after multiple sample fans demonstrate even fiber separation, stable narrow bases, and consistent opening across the tray. Also verify that the tested material, thickness, curl, length, and fan count match the intended application.
