What the product is:
YY Lash Trays D‑Curl / 0.07 / 12mm are professional YY‑style eyelash extensions made from fine 0.07 mm synthetic fibres designed to create a fuller, textured lash set.
YY lashes feature a unique split‑tip design where each lash base splits into a “Y” shape (giving four tapered tips), combining benefits of classic and volume styles for a natural‑yet‑voluminous look. 
These 12 mm length extensions are ideal for adding noticeable lift and definition while staying light and comfortable.
 
Benefits:
Using 0.07 mm YY Lashes (12 mm) provides:
Instant volume:
The double‑split structure creates more fullness per lash without needing hand‑made volume fans. 
Lightweight feel:
Fine diameter keeps extensions comfortable and lash‑safe, even with increased density. 
Faster application:
Easier and quicker to pick up and place compared with traditional volume techniques. 
Balanced definition:
Provides a hybrid effect — richer than classic lashes, softer than ultra‑dense volume fans. 
Professional finish:
Matte black finish delivers a bold, consistent look.

How to use it:
Step 1 – Prepare natural lashes:
Cleanse with a lash cleanser to remove oils and makeup.
Step 2 – Isolate one natural lash:
Use a fine tweezer to isolate a single natural lash.
Step 3 – Dip extension base in adhesive:
Place a small drop of professional lash glue onto a glue ring or palette and lightly dip the lash base.
Step 4 – Apply lash extension:
Place the YY lash onto the isolated natural lash near the lash line and hold briefly to secure.
Step 5 – Continue lash application:
Move across the lash line, choosing mapping for desired volume and symmetry.
Step 6 – Review & finish:
Brush through lashes and check for uniformity.
 
⚠️ Important:
For professional use only.
Avoid direct contact with the eyelid skin and eyeball.
Use in a well‑ventilated area due to lash glue fumes.
Perform a patch test for sensitive clients.
Ensure natural lash health can support the additional volume.
