What can I say, for this very good price (30stk. For 22) I am absolutely delighted with the quality of the vacuum cleaner bag. They fit easily in the puck 135 and do the same as the original ones, or are even better because they last longer through until they are full. The delivery does not include shipping costs also went very quickly.
My Conclusion:
I can every Kobold 135/136 owner only recommend this bag ;-)))!
