I agree that both brands have been getting worse. I was a big user of Cushelle for years :o But moved to Andrex a few years ago after Cushelle just became like tissue paper - would tear in bits just trying to tear a sheet off the roll. I have not encountered the dust thing though. I am going to keep an eye out now. Aldi has one good brand but I forget the name - has purple packaging.
Despite having "supreme" in their title, the quality of these and other Andrex wc paper (and Cushelle too) has been getting worse for years. These are not worth this price (40.6p per roll). And, they create lots of dust when tearing from the roll, coating everything in the bathroom in tissue dust.
Um... 3 x 6 = 18. Hope that helps (y)
If you look at the pattern on this toilet paper there are 4 lines of 9 dots each. 4 x 9 = 36 36 = 3 x 6 = ...um, 666 The devil is in the detail. Yes, I have got to that point in the pandemic. Tomorrow I will be reading meaning in how toothpaste tubes curl.
