Wash Your Hands!
Package Size Name: XXL, Size: 150 sheet (Pack of 12)
Great deal for the quality of these paper towels! We order them from Amazon for the office every time! They're the perfect size for use in the bathrooms or the kitchen area, so very versatile. They are very soft paper towels and absorb moisture easily.

Average Bargain Towel Performance
Package Size Name: XXL, Size: 150 sheet (Pack of 6)
These towels are cheap enough that I'll buy them in a pinch. But they are unremarkable in every way.
Their absorption is just "okay". They fall completely apart for wet-work. And they "pill", leaving traces of paper behind when wiping down anything but absolutely smooth surfaces.
I can find better bargain towels locally, assuming that I want to run out after them.
But these will do in a pinch with same-day delivery.

Works well
Package Size Name: XXL, Size: 150 sheet (Pack of 12)
There is nothing special about this product but it works fine. The only thing is that the paper towels are rough and thin, rather than a thick and soft. They fit perfectly on our paper towel rack so that’s nice. I recommend this product if you don’t care how your paper towels feel.

Thin and not as good as costco
Package Size Name: XXL, Size: 150 sheet (Pack of 12)
They are on the thin side, but the price makes them competitive

Resistant and great smell
Scent: Tropical Island
Great bags, cheaper than at the grocery store, the size is perfect, and they are very resistant. I can put a lot of weight and wet stuff in without it damaging or spilling. Also has a great smell.
