Very fine, black, silk synthetic lashes used to create mega volume are typically described as:

• Material: High-quality silk synthetic fibers, known for their lightweight and soft texture, mimicking natural lashes while providing flexibility and durability.

• Diameter: Extremely fine — usually between 0.03 mm to 0.05 mm — allowing lash artists to safely fan and apply multiple extensions per natural lash (up to 15D or more) without overloading.

• Color: Jet black for a bold, dramatic effect, offering intense depth and contrast.

• Finish: Often semi-matte to provide a natural yet rich look (less glossy than synthetic mink).

These lashes are favored in mega volume sets because their ultra-thin diameter allows for dense, fluffy fans that create a dark, full lash line without compromising the health of the natural lashes. They’re often used by advanced lash artists for dramatic, customized lash designs.
