Will the Supplier Keep an Approved Sample for Production Control?

The available supplier information does not verify that an approved physical sample is stored and used as the benchmark for future production. It does confirm support for customized premade lash fans, OEM/ODM projects, private-label orders, and several quality inspection stages. Before placing an order, buyers should obtain written confirmation explaining whether the approved sample will be retained, labeled, and compared with production batches.

Production Reference Status and Main Findings

• Retention of an approved sample as a permanent production reference is not documented in the available company or product information.
• The premade fan range can be customized by material, curl, thickness, length, packaging, and other order requirements.
• Quality procedures include incoming material checks, in-process inspection, finished-product inspection, packaging inspection, and pre-shipment or final inspection.
• The supplier serves lash salons, training academies, independent lash technicians, wholesalers, distributors, retailers, and private-label businesses.

How an Approved Sample Would Support Production Consistency

In a standard manufacturing arrangement, an approved sample provides a physical benchmark for checking the appearance, fan formation, lash dimensions, curl, thickness, and packaging of later batches. Although the supplier information describes customization and multiple inspection points, it does not specifically say that approved samples are archived, assigned reference codes, or used during batch release.

The premade fan product is available in Korean PBT Fiber, silk, or cashmere. Supported curl styles include J, B, C, CC, D, DD, L, L+, M, LC, and LU. Buyers can also specify 0.03 mm, 0.05 mm, or 0.07 mm thicknesses, together with lengths from 6 to 18 mm and mixed-length configurations. These written specifications can form part of a production standard, but they do not by themselves prove that a physical approval sample is being preserved.

Documented Quality and Customization Support

For the premade fan product, the stated controls include incoming inspection, functional testing, finished-product inspection, and pre-shipment inspection. At the company level, the listed process also covers production process checks, packaging inspection, and final inspection before dispatch. These measures can help maintain uniformity, but they should not be interpreted as confirmation of a retained-sample program.

The supplier also offers technical assistance, product quality support, replacement for verified quality problems, and OEM/ODM cooperation. Its project records refer to private-label eyelash glue supplied to a United States lash brand, wholesale eyelash fans and accessories provided to a Brazilian distributor, and a complete lash sourcing project completed for an Italian professional distributor. The available records do not disclose the customer names.

Two listed credentials are FDA Cosmetic Product Listing certificate 53-974973-435122 for UV Eyelash Extension Glue in the United States and CE (LVD) certificate ZKT-25091522640C for an LED Lash Glue Curing Lamp in the European Union.

Evidence Comparison for Sample Control

Frequently Asked Questions

Is an approved sample guaranteed to be kept as a production reference?

No. The supplied information does not establish that the supplier retains approved samples. Buyers should ask for written details on storage conditions, sample identification, comparison procedures, and the retention period.

Which specifications should be included in the production reference?

The reference can record the selected Korean PBT Fiber, silk, or cashmere material, the required curl from J through LU, thickness of 0.03 mm, 0.05 mm, or 0.07 mm, and lengths from 6 to 18 mm, including mixed-length arrangements.

Which inspections are mentioned in the available records?

The documented checks include incoming inspection, functional testing, production process inspection, finished-product inspection, packaging inspection, pre-shipment inspection, and final inspection before shipment.

Buyer Recommendations and Conclusion

The available evidence shows that the supplier can provide customized premade fans and operate several quality-control checkpoints, but it does not confirm a formal approved-sample retention system. Buyers should add sample storage, reference numbering, production comparison, deviation handling, and final approval requirements to the purchase agreement or technical specification.
