Great, comfy bed - so good I bought 2!
Size: 23 in, Size: 23 in
My dog loves this bed, I have one at home for him and one in my office at work (in pic). He sleeps so soundly on it. He’s about 7 lbs and it’s a great size for him, he likes to stretch out when he sleeps. It’s a simple, comfy bed good for dogs about 5-12 lbs. You may want to go one size bigger if your dog is 13-22 lbs.

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!

Strong, absorbent and a good price!
Package Size Name: XXL, Size: 150 sheet (Pack of 12)
These are good paper towels. Not thin at all. Strong, absorbent and capable of cleaning as well as the 'name' brand paper towels but at a much better price. I'm happy with them.

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.
