Rough Texture and Faster-Than-Expected Usage
Size: 350 sheet (Pack of 30)
I chose this bulk pack expecting a balance between softness and durability, but the overall experience has been underwhelming. Despite being labeled as 2-ply, the paper feels thinner and less cushioned than anticipated, which affects comfort during use. It also tends to tear unevenly, requiring more sheets than expected to get the job done effectively. Over time, I noticed that the rolls don’t last as long as they should based on the sheet count, likely due to the lower density of the material. While it does break down as expected for septic systems, the trade-off in quality is noticeable. Overall, it doesn’t provide the level of comfort or efficiency I was looking for in a daily-use product.

Great price! Great Paper towel!
Package Size Name: XXL, Size: 150 sheet (Pack of 2)
These Amazon brand paper towels are great! They are the multi tear size, which is perfect for different uses. The price is good and they clean windows and glass wonderfully. Softness is so so, but if you don’t have an issue with that, then these are a great buy! I definitely recommend!

Package Size Name: XXL, Size: 150 sheet (Pack of 12)
This is the best value for my cleaning company and home. They have very little to no lint which is important, theyre thick enough I dont have to double up when cleaning and you cant beat the price. Im constantly reordering these.

Does its job!
Package Size Name: XXL, Size: 150 sheet (Pack of 2)
We love these paper towels! They do the job! For Amazon basics, they hold a lot of water, wipe counters well, durable, I believe the value meets its price.
