Silk lashes are cheap synthetic eyelashes, which are lighter in color, thinner and softer than faux mink eyelashes. It is usually popular in the Asian market, because Asians have shorter eyes and it is more natural to wear synthetic eyelashes.
In terms of 3D effect, the curvature of silk eyelashes is not as good as that of mink eyelashes, but because of this, it is more popular with Asians.
