Define the fibre before you design the look
Strip-lash marketing names compress several different constructions. Faux mink usually means a tapered synthetic fibre—commonly PBT—engineered for soft volume and curl retention. Real mink uses animal fur and cannot claim vegan positioning without evidence; welfare controversies also make retail storytelling fragile unless the brand deliberately accepts that risk. Silk lashes are frequently a finer, glossier synthetic grade; some factories also advertise natural silk, so the brief must say which definition you mean. Ask for fibre diameter range, taper profile, colour, and whether clusters or strip fans are handmade or semi-automated. Style labels such as 3D/5D/25mm are commercial shorthand, not a shared measurement standard. Translate the look into length map, density, and curl code instead of relying on the buzzword alone.
Band, curl and symmetry drive returns
Band choice changes comfort and visibility: black cotton bands remain common; clear or invisible bands reduce the visible line on bare lids; softer or flatter bands can change how the strip sits. Curl codes such as C or D are widely used, with D/DD reading more lifted, but factories do not share one universal gauge. Agree a sealed sample and photograph curl after a stabilisation period rather than judging lashes immediately after heat setting. QC language from experienced lash manufacturers repeatedly flags shedding, left-right mismatch, glue residue, brittle fibres from overheating, and curl drop from under-setting. AQL sampling commonly discussed around 2.5 major / 4.0 minor in factory guides is a conversation starter for inspection severity, not a certificate that your SKU already passed.
Match packaging to the channel
Private-label lash work is often packaging-led: trays, back cards, magnetic boxes, drawer boxes, acrylic cases and multi-pair lash books. Decide whether the unit is a single pair, a kit or a book before requesting print quotes. Logo process, tray colour and insert fit should be approved with the real lash volume inside the pack. If lashes will sit beside PRETTY brushes in a gift or hero kit, keep brush and lash approvals on separate sample lines. PRETTY does not present itself as a dedicated false-eyelash factory on the beauty-tools pages; production arrangements for lashes are confirmed at quotation. Working MOQ for the new category is discussed as MOQ 500, unit/assortment confirmed at quotation.
Claims and compliance need separate owners
In the United States, FDA materials treat eye-area cosmetics—including false eyelashes and adhesives—as products that must be safe for their intended use and properly labelled. Adhesives may introduce latex or other sensitizers even when the strip fibre is synthetic. In the EU, finished lashes as articles generally fall under product-safety rules such as GPSR rather than the cosmetic-mixture regulation; adhesives and liquids in a kit still need their own assessment. These are planning reminders for your compliance counsel, not a statement that any PRETTY lash SKU is certified; such claims require evidence.
Compare suppliers with one brief
Send each candidate the same fibre definition, length map, band preference, defect list and packaging concept. Score shedding control and pair matching as heavily as price. Ask how curl is set and when it is measured. Keep adhesive and applicator kit components on separate lines so a fibre decision does not silently inherit an unreviewed glue formula. Write acceptance criteria in plain language a new teammate can apply without a factory tour. Photograph approved and rejected examples side by side, keep batch codes on the record, and note which checks are visual, dimensional or performance-based. When a supplier offers a catalogue substitute, re-run the same checks rather than assuming equivalence from a similar photo. If marketing needs a stronger claim later, route it through the claim register instead of editing the specification after bulk has started. For cross-border launches, list destination labelling owners early so pack artwork does not stall after the product sample is already loved. Keep commercial open points visible: undecided assortment mix, undecided secondary packaging, and undecided combined shipment should remain marked undecided until the quotation closes them. A short weekly decision log during sampling usually costs less than one rushed reprint. Finally, confirm who owns after-sales defect photos and replacement rules before the first retail delivery leaves the dock.

Checklist
- Fibre definition states faux mink / mink / silk meaning in writing
- Length map, density and curl code replace vague 3D/5D labels
- Band type and comfort expectations are approved on skin or mannequin review
- Shedding, symmetry, glue residue and curl retention are on the QC list
- Retail pack is fitted with the real lash volume
- Adhesive and kit liquids are scoped separately from the strip
- Animal-derived fibre is excluded if the brand needs vegan positioning; do not claim vegan without evidence
Frequently asked questions
Faux mink vs mink: which should a new brand choose?
Most new private-label lines choose faux mink for design flexibility and simpler claim control. Real mink is a deliberate positioning choice with welfare and labelling consequences.
Are silk lashes natural silk?
Not necessarily. Ask whether silk means a finer synthetic fibre or a natural-silk construction, then lock that definition into the specification.
What defects cause the most complaints?
Shedding, mismatched pairs, harsh bands and curl that relaxes after storage are repeatedly cited in manufacturer QC guides.
Can lashes be quoted with brush sets?
They can be discussed in one project conversation, but keep specifications and sample approvals distinct unless the quotation explicitly bundles them.
