I bought this vacuum cleaner bags in sets of 5 for 10. There are original bag, the same who, TH-VC 1820/1 S were included with my Einhell Wet-dry vacuums. The quality is good, the bag holds the rubber ring securely on the neck and there is no reason here not to award 5 stars.
ATTENTION: I delivered the wrong bag Amazon. These are shown significantly higher as in the photo and probably the 30l waste collecting bags. I wrinkle to bottom, they are also attached.
