A kilometer of toilet paper

Earlier this year, 7-Eleven made headlines for introducing "Japan's longest roll of toilet paper". At 356 meters long, it is definitely on the longer side. But it is actually not the longest roll of toilet paper in Japan. There is a product called Midoru Janbo, Middle Jumbo presumably in English, which is one kilometer long.

The reason 7-Eleven gets away with its claim is because their 356 meter long toilet paper is the longest that is for household use. Whereas Middle Jumbo is for commercial use. There was, in the past, an Ultra Jumbo toilet paper roll that was 1.2 kilometers long, but it went out of production because it was too big for the vast majority of commercial use toilets. 

Anything longer than 50 meters of toilet paper is considered long, as, in Japan, 50 meters is the average length of a roll of toilet paper. 7-Eleven went with 356 meters long toilet paper as it is 7.11 times longer than the average roll of toilet paper! With the number of times that toilet paper has sold out during a natural disaster (and during Covid) in Japan, long toilet paper rolls certainly have an appeal. But I think 7-Eleven's 356 meters is more appealing than a kilometer of toilet paper! What do you think?
