To highlight the vaccum canisters that VWNOS sells we decided to take one apart as a quality assurance test. From the pictures provided please see these are still of high quality and show no signs of deterioration. Our canisters are stored in prime conditions so that we have an assurance we are providing our customers with quality.
Here's a picture after we pryed off the side of the vacuum.
And here is the material from inside. The edges are frayed a little from our tools but otherwise in pristine condition.
