Price includes VAT. Free Delivery on orders over £100

Soft 4D Texture with Simple Individual Application

Our YY Single Length Lash Trays are designed for lash artists who want the fullness and texture of a 4D lash with the straightforward placement of an individual extension.

Each YY is formed from four fine fibres arranged into a distinctive double-Y shape, creating a soft, textured effect while retaining a single structured base for controlled application.

With approximately 1,600 YY lashes per tray, single-length trays are ideal for topping up the sizes you use most frequently.

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, creating a soft 4D effect, while the single base allows you to apply one YY to one suitable isolated natural lash.

They’re a great option for artists who want more fullness and texture than a traditional classic extension without needing to create handmade volume fans.

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
• Ideal for light volume and textured styling
• Faster than creating individual handmade volume fans
• Structured base for controlled pickup
• Approximately 1,600 YY lashes per tray
• 16 rows per tray

Why Choose Single Length Trays?

Single-length trays make it easy to replace the sizes you use most without repeatedly purchasing another mixed tray.

They’re particularly useful for busy artists who already know which lengths they reach for regularly and want greater control over their lash stock.

Available in single lengths from 8mm–15mm.

0.05 or 0.07 – What's the Difference?

Our YY lashes are available in 0.05 and 0.07 diameters.

Each YY contains multiple fine fibres, so the combined weight of the extension, its length and the condition of the natural lash should all be considered when choosing the appropriate option.

Always select lashes according to the health and strength of the client's natural lashes, rather than choosing solely by the finished effect you want to create.

Soft Matte PBT Fibre

Made from high-quality PBT, our YY lashes have a soft, flexible feel with a rich matte black finish.

The structured base allows controlled pickup while the separated fibres create the distinctive soft YY appearance through the lengths and tips.

Looking for more variety in one tray? Our YY Mixed Trays contain 8mm–15mm lengths, and Brown YY Mixed Trays are also available for clients wanting a softer alternative to black.

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.
