Procter & Gamble has created a new toilet-paper roll for millennials and older people who live alone and have limited storage space.

A P&G executive told The Wall Street Journal that the Charmin Forever Roll, at nearly three times the size of a conventional toilet-paper roll, could last up to three months in a single-person household.

Companies are rethinking how they package food and household goods to accommodate the growing number of Americans who are living alone, particularly as millennials delay marriage and having kids.

Among the companies making packaging changes is Procter & Gamble, which created a toilet-paper roll designed to appeal to people who live alone and may have limited storage space, Ellen Byron reported for The Wall Street Journal.

At nearly three times the size of a conventional toilet-paper roll, the new Charmin Forever Roll is massive.

One Forever roll can last up to three months in a single-person household and requires half as much storage space as conventional rolls, a P&G executive told The Journal.

"Now go up to ONE MONTH before changing your roll," an ad for the Charmin Forever Roll says. "With Forever Roll, you can go longer between roll changes without sacrificing your comfort. It's super convenient and long-lasting, so you have one less thing to think about!"

According to The Journal, P&G created the Forever Roll with two types of single-person households in mind: "urban millennials and aging consumers."

The Forever Roll comes in two sizes: multiuser, 12 inches in diameter, and single-user, 8.7 inches in diameter, according to Charmin's website. Conventional rolls measure roughly 5 inches in diameter.

The Forever Roll even comes with its own hardware.

Charmin has a $30 Forever Roll "starter kit" on its website that includes a brushed-stainless-steel roll holder, either free-standing or wall-mounted, and three rolls.
