"The toilet paper roll is about to undergo its biggest change in 100 years: going tubeless. On Monday, Kimberly-Clark, one of the world's biggest makers of household paper products, will begin testing Scott Naturals Tube-Free toilet paper at Walmart and Sam's Club stores throughout the Northeast. If sales take off, it may introduce the line nationally and globally — and even consider adapting the technology into its paper towel brands. No, the holes in the rolls aren't perfectly round. But they do fit over TP spindles and come with this promise: Even the last piece of toilet paper will be usable — without glue stuck on it."
