The comfort of the transparent stem and the black eyeliner varies according to the individual's feelings. I personally think that the black stem is more comfortable, the black is the cotton stem, and it is easier to inhale the glue, so that the eyelashes are more firmly bonded. The transparent stem is a fish thread that is not very easy to inhale. From the perspective of the eyeliner, the color of the transparent stalk eyeliner is more flexible. Black is best with a black eyeliner.
