The best ever paper towels
Package Size Name: Family Triple Roll, Size: 141 Sheets (Pack of 12)
These are hands down the best paper towels I have ever used. If you haven’t tried them yet, you absolutely should. They truly feel more like a soft cloth than a paper towel, and the absorbency is incredible. They’re durable, super soft, and handle messes so well without falling apart. I am officially a buyer for life and won’t be going back to anything else!

These are the best paper towel ever!
Package Size Name: Family Triple Roll, Size: 141 Sheets (Pack of 12)
The reason I say these are the best paper towels is because they are more like a cloth than actual paper. If you're doing something larger like cleaning the kitchen sinks you can usually get by with just one. You can wet it down, ring it out and continue working. When it's time to dry, these soak up so much more liquid than any other towel... It's crazy! They are a bit on the expensive side, but you'll use so fewer towels that it makes up the difference.

Strong, mighty and reusable.
Package Size Name: Triple, Size: 141 Sheets (Pack of 2)
I love these specifically for our RV because they work great to take my makeup off at the end of day as well. These really are different and more durable then most others on the market. Can even be rinsed and reused before discarded if need be.

Close to a cloth
Package Size Name: Triple, Size: 141 Sheets (Pack of 16)
Hi All, These are simply terrific paper towels that are close to grabbing a cloth. They come in triple size rolls which we find helpful. I get the ones that can tear at a half size sheet, and find the roll last longer when you don't have to use a full sheet for everything. For paper, these are softer than most, and don't have that sandpaper feeling like so many do. I think you'll like them. Prices and sizes change depending on the stock available so watch for the right price for the right rolls you prefer.
