The Companion Eyelash Glue ($10 USD) comes in a convenient tube with a fine brush applicator. The glue stays on well, as it definitely took some scrubbing to get that swatch off in the photo below. It is a thin formula that goes on white and dries clear. It isn't goopy like the Duo glue, which could be good or bad depending on your taste. I prefer a slightly thicker formula since I'm still a false lash noob, and I find that the thicker glues are more forgiving.
