What are flat lashes？
Flat lashes — also called ellipse lashes or cashmere lashes — are eyelash extensions with an oval base instead of the round base on standard classic lashes.
A round classic lash sits on the natural lash at about a 60° contact angle. A flat lash wraps around it at up to 120° — twice the bonding surface. The wider grip holds tighter and keeps fills lasting longer.
The flat base has a curved underside that cups the natural lash like a cradle. It locks the extension in place and stops the twisting or spinning you sometimes see when round classics sit on fine, straight natural lashes.
Weight is the other big difference. RY Lashes flat extensions run about 75% slimmer than a round classic of the same visual width. A 0.20mm flat lash looks as wide as a thick classic but weighs close to a 0.07mm volume fiber. Clients get bold sets without dragging on their natural lashes.
Our flat extensions use Korean PBT fiber with a matte black finish and Y-split tips. The split tip gives each lash a soft, feathery edge — one extension pulls off the wispy look that usually takes a 2D or 3D volume fan.

Flat Lashes Factory Supplier
OEM Flat Lash Extensions Manufacturer & Private Label Lash Extensions
RY Lashes Factory has made flat lash extensions for over 8 years. We sort Korean PBT fiber and test thickness, handcraft each lash, set the curl, build the tray, and run quality checks before shipping.
Every tray goes through a five-stage QC. We check fiber consistency, curl accuracy, length, tip split, tray layout, and backing tape grip. Trays that miss our tolerance range get remade — not downgraded and shipped.
Before your order leaves the factory, we send inspection photos and a short video so you can confirm the product matches your spec.
RY Lashes Factory and our products hold MSDS, SGS, and ROHS certifications. Safety testing covers fiber toxicity, skin irritation, and adhesive compatibility.

FAQ About Ellipse Flat Lash Extensions
RY Lashes flat extensions use Korean PBT (polybutylene terephthalate) fiber imported directly from Korea. PBT is a synthetic material that holds curl shape for 6+ months after heat-setting, resists moisture and humidity, and feels soft against the skin. All our PBT fiber is cruelty-free and vegan.
Classic lashes have a round cross-section. Flat lashes have an oval (ellipse) cross-section with a concave underside. This concave shape cradles the natural lash and bonds at up to 120° of contact — compared to about 60° for round classics. Flat lashes are also 75% lighter than a classic lash of the same visual diameter, and the Y-split tips add texture that a single-point classic tip can’t achieve.
Yes. Flat lashes are one of the best options for clients who want a full, dramatic look but have natural lashes too fine or fragile for standard classic extensions. A 0.20mm flat lash gives the visual impact of a thick classic extension but weighs roughly the same as a 0.07mm volume fiber — putting almost no strain on the natural lash follicle.
We produce flat lashes in J, B, C, CC, D, DD, L, and M curls. Custom curl types can be developed through our OEM service if you need something outside our standard range.
Yes. Our private label service includes logo printing on tray labels (paper coating included free, silver foil available), custom tray sleeves, and branded outer boxes. Our design team provides free design support for bulk orders.
Our MOQ for private label orders is low enough for lash startups and small salons to get started. Contact us for specific quantities — these vary depending on the number of SKUs and packaging type.
RY Lashes is a direct factory — not a trading company. We import Korean PBT fiber, manufacture in our own facility, run a three-stage QC process, and ship worldwide.
You get factory pricing, product consistency, and a single point of contact for everything from R&D to delivery.
With proper application and aftercare, flat lash extensions typically last 3–5 weeks before a fill is needed. The wider bonding surface of the flat base tends to improve retention compared to round classic lashes.
Yes. Flat lashes mix well into hybrid and volume sets. Many lash artists sprinkle flat extensions into a volume set to add texture and depth, or use them as the classic component in a hybrid design.
Flat lashes should be attached from the top or bottom of the natural lash — not from the side. The wide surface of the oval base needs to sit flush against the natural lash for the strongest bond. Dip 1–2mm into adhesive and withdraw slowly.
Yes. We ship to 50+ countries via DHL, FedEx, UPS, and sea freight. Express shipments arrive in 5–7 business days to most destinations.
