Where are the Nail Paint Testers?

Nail products have taken off in a really big way in India.

We have brands coming up with collections exclusively based around nail paints. For example the recent Pop Tints Launch by Lakme.

Most of these products cost anywhere between 150 to 400 rupees. I'm talking mostly about drugstore brands here: Lakme, Maybelline, Revlon, Colorbar & Faces.

However neither of these brands seem to think it is important to offer nail paint testers to customers. It is present neither at their kiosks in department stores, nor at their flagship stores (at least not in Infinity - II. I was there yesterday and at all stores they didn't have testers for nail paints).

I don't get why they would not offer testers for nail paints to customers. It can't be because the range is too big. They have a similarly big range in lipsticks - all of these brands - and they seem to offer testers there. So why leave out the nail paints?

Sometimes some SAs let you try them on the sly from a new bottle. But it all depends on the SA, some are sticklers for rules and won't budge.

Is it because nail paints dry out once opened? Maybe companies do have a valid reason for not offering testers. Maybe it gets infected with bacteria and is a liquid product - but then so are foundations! And by that count there should be absolutely no testers for liquid eye liners.Is it because then they will have to offer acetone to customers as well?

But I'm just curious. As a consumer, I would obviously like to be sure before forking out the dough.

Does the lack of nail paint testers bum you out as well? Why do you think they do it?
