Soft 4D Texture with Simple Individual Application
Our YY Lash Mixed Trays are designed for lash artists who want to create soft, textured and fuller-looking sets without handmade fan creation.
Each YY extension is formed from four fine fibres in a distinctive double-Y shape, creating a soft 4D effect while retaining a single structured base for straightforward application.
The mixed tray contains 8mm–15mm lengths, giving you a versatile selection for complete lash sets and creative mapping.
What Are YY Lashes?
YY lashes are pre-formed extensions made from four fine fibres arranged into a double-Y structure.
The fibres separate through the length of the extension to create a soft, feathered effect while the single base allows the YY to be applied individually to one suitable natural lash.
They sit beautifully between traditional classic lashes and fuller volume styling.
Why Choose YY Lashes?
- Pre-formed 4D YY design
- No handmade fan creation required
- Applied individually to one suitable natural lash
- Creates more fullness than a traditional single classic extension
- Soft, wispy and textured appearance
- Great for light volume and textured styling
- Faster than creating individual handmade volume fans
- Structured base for controlled pickup
- 8mm–15mm mixed lengths
Simple Individual Application
YY lashes are picked up and placed individually, making the application process familiar to artists comfortable with classic-style placement.
Take care to pick up the YY evenly from the strip so the base and double-Y structure remain intact.
Apply one YY extension to one suitable isolated natural lash.
0.05 or 0.07 – What's the Difference?
Our YY lashes are available in 0.05 and 0.07, giving you different options depending on the natural lashes and the finished effect you want to create.
Remember that each YY contains multiple fibres, so the combined weight of the extension should always be considered.
Choose the diameter and length according to the health, strength and condition of the client's natural lashes.
Mixed Lengths 8–15mm
The mixed tray contains lengths from 8mm to 15mm, making it a versatile option for:
- Complete YY lash sets
- Soft textured styling
- Light volume effects
- Wispy lash maps
- Artists trying YY lashes
- Building a core lash collection
Mixed trays are also useful for discovering which lengths you use most frequently before investing in single-length trays.
Soft PBT Fibre
Made from high-quality PBT, our YY lashes have a soft, flexible feel and deep black finish while maintaining the distinctive YY structure needed for consistent application.
Not Tried YY Lashes Before?
We also offer a 5-row YY Lash Sample Tray, giving you the chance to test the curl, diameter, pickup and finished effect before purchasing a full-size tray.
Tweezer Recommendations
YY lashes have a wider, structured base, so even pickup is important to help maintain their shape during application.
Suitable options include:
- Hybrid 45° Tweezers – Fibre Grip
- Angled Volume Tweezers – Fibre Grip
- All Purpose Curved 60° Tweezers – Fibre Grip
Choose the tweezer that gives you a secure, even grip without twisting or distorting the YY during pickup.
