Some customers say that our cards are more expensive than others and they bought our cards at last. Why? That’s because our price base on the high quality of the marked cards. And we really don’t want to sell products in poor quality. You can just compare the effects of different marks working with different lenses and then choose what you like.

In the Form D, we can’t see the marks of the cards clearly because lenses in poor quality can’t work with poor marked cards well.

In the Form C, the marks look normal. The lenses is really good, however the marks of the marked cards are not so clear to see.

In the Form B, the marks are better because the cards are really good, though this kind of lenses isn’t the best.

In the Form A, you can see the marks most clearly, because good lenses works perfectly with good marked cards.

After comparing the results of these marked cards and lenses, do you still prefer the cheap ones? Which one is your ideal choice, A, B, C or D?

A. good lenses + good cards ==== perfect marks

B. poor lenses + good cards ==== better marks

C. good lenses + poor cards ==== normal marks

D. poor lenses + poor cards ==== poor marks
