Is it good for free eyelash sample?

Many customers ask me for free eyelash samples?

Every time, I say sorry, but you can order only one product to test our quality.

Dear customers, there is no free lunch in the world. Even if you meet customers who provide samples for free, I can make a bet with you. Their quality must be unsatisfactory.

Otherwise, the company will not sell a good quality product? Instead, if I will give it to you free of charge, are you think you are a very special customer?
