Custom 16-Row 0.15mm C Curl Flat Lash Extensions, 8–14mm

This product page presents a custom sourcing configuration for 16-row 0.15mm C curl flat lash extensions in mixed 8–14mm lengths. It is intended for lash brands, distributors, importers and professional beauty supply companies that need a clearly defined specification for supplier matching, sample testing and private label development.

Target Specification for Supplier Matching

Why Source 0.15mm Flat Lash Extensions?

Buyers often compare flat lashes with conventional round-base classic lashes when developing a professional extension range. A flat-base design may create a different visual profile and bonding surface, but the actual result depends on the supplier’s fiber construction, base width, tip treatment and manufacturing consistency.

For this reason, the term 0.15mm flat lash extensions should not be treated as a complete purchasing specification. Buyers should also confirm:

• The measured thickness and width of the lash fiber
• The shape and consistency of the flat base
• Whether the product uses a single-tip or split-tip appearance
• The softness, finish and color consistency of the fiber
• The curl stability across different lengths and production batches
• How easily the lash strips release from the tray during professional use

Planning an 8–14mm Mixed Length Lash Tray

An 8–14mm mixed length lash tray can help professional buyers combine several commonly requested lengths within one retail or salon package. However, “mixed length” does not define how many rows of each length are included.

Confirm the Row Allocation Before Production

For a 16-row tray, the buyer should prepare a proposed row allocation based on the intended lash map and customer demand. For example, shorter lengths may require fewer or more rows than the middle lengths. The final allocation should be confirmed after reviewing technician feedback and supplier capabilities.

What to Check in a 16-Row Flat Lash Tray Sample

Sample evaluation should be completed by trained lash professionals before a bulk or private label order is approved. Useful inspection points include:

• Length accuracy: Compare the physical lashes with the labeled 8–14mm specifications.
• Curl consistency: Check whether the C curl remains visually consistent between rows and lengths.
• Base profile: Inspect the flat-base shape and determine whether it matches the intended application technique.
• Strip performance: Test removal, positioning and adhesive residue on the working strip.
• Row quantity: Confirm that the tray contains the agreed 16-row layout.
• Fiber appearance: Compare color, sheen, softness and tip consistency under the same lighting.
• Packaging protection: Check whether the tray and box protect curl and row alignment during transportation.

Private Label Packaging for Flat Lash Extensions

Private label development may include a branded outer box, tray card, length labels, curl and diameter markings, barcode position and other printed information. Packaging should not be finalized until the physical tray size and row arrangement have been confirmed.

Important packaging details include:

• Correct product name, curl, diameter and length range
• Clear identification of mixed-length row allocation
• Consistent SKU and barcode structure across the product range
• Country-specific labeling requirements provided by the buyer
• Protection against tray movement and box deformation in transit
• Artwork approval and color checking before bulk printing

Supplier Matching and Repeat-Order Control

Pingdu has a broad eyelash supply network, but specifications can vary between suppliers. Our role is to support supplier matching, specification confirmation and sample-based development according to the buyer’s target product rather than presenting every configuration as fixed inventory.

For repeat orders, brands should retain an approved sample and a written specification sheet covering:

• Approved fiber appearance and flat-base profile
• 0.15mm diameter requirement and testing method
• C curl comparison standard
• 8–14mm length allocation across all 16 rows
• Tray, strip, label and outer box requirements
• Acceptable tolerances and inspection points
