The screw-top container, which incorporates a fine-point felt-tip applicator, is about four inches long and half-an-inch in diameter. It is comfortable in the hand and neat enough to fit easily into a small cosmetic purse. This is the end of the good news.
The instruction to shake before use is in tiny printing on the side of the container. I shook it vigorously before unscrewing and thought the applicator tip looked nicely pointed without being too long. Try as I might, I could not get the eye-liner to flow from the applicator tip. The line was weakly coloured, grey rather than black and intermittent; the tip glided over the skin but it did not leave any eye-liner in its wake. It needed several quite hard strokes to get any kind of line, whether I used the point or the side of the applicator. Yes, I did give it another good shaking but to no avail.
Perseverance paid off but only in the short-term because by lunch-time the liner had almost disappeared and needed to be renewed. I tried again, with the same miserable results. I did find that when applied to the back of my hand, the cosmetic flowed more freely although it still left tram-tracks rather than a single line. (And I was not pressing on the tip.) From this I assume that you need to lie down to put on your eye make-up because it worked when the point was held tip-down but not when it was held tip-up.
It is possible the item was simply a faulty glitch in a batch of perfect ones but I was very disappointed indeed with its performance.
