chain of little bead.
this is another kind of nail decorations, very elegant on nail.
after base coat, apply polish of two kinds color, silver and purple. keep the line clear.
put the chain on line, (here pls keep in mind, manage to place on nail firmly on your first try)
you can stick with glue if you're worried that the chain may fall off.
This design from Tea ‘s review, a very impressive nail tech.
