Charmin has created a roll of toilet paper for the millennial generation that lasts for months

Businesses are rethinking how they pack food and household items to meet the growing number of Americans living alone, especially when the millennial generation is delaying marriage and children.

Among the companies making packaging changes are Procter & Gamble Co., which has created a new toilet paper roll designed to appeal to people living alone and with limited storage space. Ellen Byron reports in the Wall Street Journal.

The new Charmin Forever Roll Roll is almost three times bigger than a conventional roll of toilet paper.

But a roll can last up to three months for a one-person household and Forever rolls require two times less storage space than conventional rolls, said a P & G official at Newspaper.

"Now go to ONE MONTH before changing roles," reads in the advertisement for the Charmin Forever roll. "With Forever Roll, you can spend more time between bearing changes without sacrificing your comfort.It's super convenient and durable, so you have one less thing to think about!"

According to the newspaper, P & G has created the new Forever Roll with two types of one-person households: millennials in urban and aging consumers.

The Forever roll comes in two sizes: multi-user, which measures 12 inches in diameter, and single user, which measures 8.7 inches in diameter, according to the Charmin website. In comparison, conventional rollers measure about five inches in diameter.

The Forever Roll even comes with its own hardware.

On its website, Charmin offers on its website a Forever Roll "starter kit" including brushed stainless steel roll holders, to be mounted or wall mounted. Starter kits, which include three reels, cost $ 29.
