How to make sure the quality of bubble umbrella is good in production?

Unlike other umbrellas, bubble umbrella need to have a clean plant for production. Since the fabric is easily broken by shape stuff and the surface of the fabric need to keep clean, workers must take more care during the production.
We produce high quality bubble umbrellas in a very clean plant. To make sure the fabric is clean, the worker worn a glove and assembled the clear umbrella fabric with an umbrella frame. Her hands didn't touch the fabric directly. We pay more attention to the goods quality and conduct the supply chain management during the whole production for making sure the quality of bubble umbrella is good.
