The best quality / quantity / price for scraps of this style on Amazon. The dimensions are ideal for cleaning glasses (like those of opticians); they are a little thicker, it's a + because it does not wrinkle in all directions during cleaning. Without any added product they nettoyent my glasses perfectly. Add to this that you have 10 to 0.90 euro unit; ask for more or less would be unrealistic. This is also great to be several: I have one on me constantly in my jacket, and my home was within reach.
I'm really delighted. If I had to overcome the ten (it will take some time) I will take it without hesitation!
