To the Mega volume set it is possible to carry all subsequent volumes - 3D, 4D, 5D, 6D and so on. Such a beautiful story is preferred by lovers of very pronounced eyes, and those who want to go with eyelashes as long as possible.
For one natural cilia are attached 3 to 7 (or more) artificial, which gives eyelashes extra pomp and volume. At the same time, for the bulk extension techniques, the thinnest cilia are used. They are very light, so you can not be afraid for their "native" cilia. If you used to do classical build-up and you liked it, then I'm sure that from 3d you will be completely ecstatic, and your cilia will feel the load commensurate with the classic build-up.
