How do I personally check the quality of the material?

I would like to mention that we are also suppliers for supermarkets like  E.Leclerc and Mercator and we do not want to face problems with our items being returned to us.

That is why I simply wash each product at 90 ° C and look at two things:

1. Is the color still the same?

2. Has the size changed significantly?

If the product does not lose color and does not lose its elasticity or size, it is suitable for sale.
