We have even lost money after sewing some of our products with the poor-quality Velcro the supplier delivered.
The difference between the sample and the delivered Velcro is obvious — the thickness is not the same, the holding strength is much weaker, and several of the Velcro pieces arrived deformed, which clearly shows the poor quality.
Even with clear photos and videos, the supplier keeps insisting it is the same quality, which is not true.
