The difference between these two figures is due to a very tight winding during rolling leads but to an additional loss of comfort.
Speaking of comfort:
The figure shows a soft, commercial toilet paper. One does get a rough stone, extremely thin recycled paper. Rough recycled paper would be ok if the documents (there are, admittedly, 3) would have the standard thickness. Instead, "fluddern" the thin layers just around the backside.
The height of a role is "only" 1 to 2 mm less than commercially. Therefore, the outer diameter is about 20mm lower than commercially. But then the diameter of the cardboard tube approximately 7mm is greater than commercially available, which I think is the greatest "Bes *****"!
The added absence of level of my review, I ask you to forgive me, but as "bes *******" I was at Amazon never !!!!!
So: Stay away !!!
