I have in my possession two belts of the same brand, but they are really different. (see pics below)
The one on the right: It has irregularities, and is rather rigid. It has fairly large pores.
The one on the left : It is more uniform, and has a slightly lighter shade. It is also more flexible and softer. The pores are less visible and narrower.
My question is: from these characteristics, is it possible to know if one of the two belts is more qualitative than the other ? I have to keep only one of them, and i don't want to do the wrong choice.
Thanks by advance for help
