Each lash is individually implanted and rooted into the silicone eye, the way real lashes sit in a lid. They are non-detachable — there is no strip to lift off. That is what lets the lash line take repeated isolation, tugging and adhesive practice without coming away.
Strip-style practice lashes are a band of lashes glued onto the surface. Under normal drilling they shed, slide and peel at the edges, and the glue residue makes the surface messy. A class of students working the same head will strip it bare in days — and a lash line that keeps failing teaches the wrong muscle memory.
For an academy the cost is double: you re-buy heads constantly, and students practise on a surface that does not behave like a client. A hand-implanted lash line behaves consistently from the first lesson to the last, so the head is a stable teaching tool rather than a disposable.
