Flat Lash Private Label Spec Sheet: Naming, Fiber Profile and Sample Notes
Share
A flat lash private label spec sheet protects the buyer from one of the most common launch problems: beautiful packaging with unclear product specs. Flat lashes, also called ellipse lashes in many wholesale ranges, need more than a logo file. The buyer needs a written product record that connects naming, fiber profile, curl, thickness, 8mm-15mm length structure, tray labels, sample notes, packaging proof, and reorder codes.
This article is not a general sample checklist. For sample testing details, use LASHMAITRE's flat lash sample check before wholesale orders article. This guide focuses on the document a buyer should approve before private label flat lash production.
Why a Flat Lash Spec Sheet Comes Before Packaging
Private label buyers often start with packaging because it is visible and exciting. The tray box, logo label, sleeve, insert, and product page images feel like the launch. But if the product record is incomplete, packaging approval can happen too early.
A flat lash private label spec sheet should answer:
- What is the product called?
- Is the product described as flat lashes, ellipse lashes, or another approved name?
- What fiber profile language will appear in buyer-facing material?
- Which curl, thickness, and length structure are approved?
- What tray label fields are required?
- Which sample photo is the approved reference?
- Which packaging proof matches the approved tray?
- What reorder code should be used next time?
The existing private label lash extensions page can support the broader service path. The spec sheet is the working file that keeps the private label flat lash product repeatable.
Start With Naming and Fiber Profile Language
Naming should be decided before artwork is finalized. A buyer may use "flat lashes," "ellipse lashes," or another brand-specific product name, but the internal product file should define the technical meaning clearly.
Use this naming table:
| Spec field | Example decision | Why it matters |
|---|---|---|
| Product family | Flat lash or ellipse lash | Separates the tray from classic and premade fan products |
| Buyer-facing name | Brand-approved product name | Keeps product pages and packaging consistent |
| Fiber profile note | Flattened or elliptical profile | Helps sales teams explain the product accurately |
| Product boundary | Not premade fans | Prevents incorrect volume fan language |
| Label format | Curl, thickness, length, code | Supports packing and reorder checks |
Flat lashes should not be described as premade fans. They are lash extensions with a flattened or elliptical profile, arranged in dense strip rows. That product boundary belongs in the spec sheet so future packaging and listings do not drift into the wrong category.
Record Curl, Thickness, and Length Structure
The spec sheet should make the physical tray easy to repeat. For flat lash private label work, record every field that affects the product and label.
Include:
- Curl, such as C, CC, or D.
- Thickness.
- Length format.
- Visible length range, such as 8mm-15mm when using a full tray range.
- Tray row notes.
- Fiber profile language.
- Label text.
- Packaging version.
- Approved sample image.
If the buyer is still deciding whether flat lashes belong in the first launch, use the flat lash product line planning guide first. A spec sheet works best after the buyer has chosen a narrow starter range.
Add Sample Notes Without Repeating the Whole Test
The flat lash private label spec sheet should include sample notes, but it does not need to replace the full sample approval file. Keep the spec sheet concise. It should point to the approved sample and summarize the decision.
Useful sample notes include:
- Pickup feedback.
- Curl consistency.
- Row alignment.
- Fiber profile confirmation.
- Label accuracy.
- Packaging comments.
- Buyer approval date.
- Any change required before bulk production.
The spec sheet should not contain vague comments like "good quality" or "looks nice" without details. Those notes do not help the next reorder. A better note is: "D curl, 0.15, 8mm-15mm mixed tray approved with updated label code FL-D015-MIX."
Connect the Spec Sheet to Label and Packaging Proof
Private label flat lash packaging needs a direct connection to the approved tray. Before printing, compare the spec sheet against the packaging proof.
Check:
- Product name.
- Fiber profile wording.
- Curl.
- Thickness.
- Length range.
- Tray code.
- Box or sleeve artwork version.
- Label position.
- Barcode or SKU code if used.
The FDA cosmetics labeling guide is a general reference for cosmetic labeling context. For lash buyers, the practical point is that product information should be organized and consistent before packaging is printed.
For more label-specific planning, use LASHMAITRE's lash tray labeling guide.
Use a Versioned Approval File
A spec sheet should have a version number or approval date. Without version control, the buyer may approve one sample, revise the label, request a packaging change, and later reorder from an older file.
Use a simple version format:
| Version field | Example |
|---|---|
| Product code | FL-CC015-MIX |
| Product name | Private label flat lash tray |
| Version date | 2026-06-03 |
| Sample status | Approved |
| Packaging status | Label proof approved |
| Reorder note | Use same tray, label, and box file |
The ISO 9001 quality management systems standard is a general reference for documented and repeatable requirements. A lash buyer does not need a heavy documentation system, but the approved flat lash private label spec sheet should be clear enough for the next order to match the original approval. Reference: ISO 9001:2015.
Turn the Spec Sheet Into a Reorder Tool
The best flat lash private label spec sheet is useful after the launch. It should help the buyer reorder without rebuilding the project from memory.
Before bulk production, confirm:
- The approved tray photo is attached.
- The approved packaging proof is attached.
- Product family and fiber profile wording are locked.
- Curl, thickness, and length structure match the sample.
- The label fields match the tray.
- The reorder code is easy to find.
- Any rejected versions are marked clearly.
- Buyer approval is recorded.
If the buyer needs samples before final approval, use the lash extension samples page to request a sample-first path. If the buyer is ready to discuss the full private label order, use the wholesale lash extensions inquiry page.

FAQ: Flat Lash Private Label Spec Sheet
What should a flat lash private label spec sheet include?
It should include product name, fiber profile wording, curl, thickness, length range, tray label fields, sample notes, packaging proof, approved images, and reorder code.
Should the spec sheet say flat lash or ellipse lash?
Use the name approved for the buyer's product line, but define the fiber profile clearly in the internal file so labels, listings, and reorder notes stay consistent.
Do flat lash labels need length information?
Yes. The label should show the correct length or length range. If a tray uses an 8mm-15mm range, that range should match the actual approved tray.
Can packaging be approved before samples?
Packaging design can be drafted early, but final packaging proof should be checked against the approved tray specs and sample notes before bulk production.
How does the spec sheet help with reorders?
It gives the buyer and supplier one approved file for product name, fiber profile, curl, thickness, length, label, packaging, sample image, and reorder code.
Conclusion: Make the Product File as Clear as the Packaging
Private label flat lash packaging should look polished, but the product file is what keeps the line repeatable. A clear spec sheet protects naming, fiber profile language, curl, thickness, length structure, labels, packaging proof, sample approval, and reorders.
Send LASHMAITRE your flat lash product name, fiber profile language, curl and thickness plan, 8mm-15mm length structure, tray label draft, packaging artwork, sample request, and reorder target so we can prepare a focused private label approval path.
Buyer next step: A flat lash private label spec sheet should connect fiber profile and packaging wording with LASHMAITRE lash quality control before the buyer approves repeat tray production.
