So disappointed in this product. It was not as pictured. The picture shows a more square bag. The one I received was more slouchy. I purchased it to use for work for a laptop. Theres no way it would fit. I ended up donating this bag.

Ex Output:
negative

When the ache/pain in my upper back won't stop, I always turn to this product. It takes away the pain almost immediately. It is adjustable and comfortable to wear. I love it!!

positive

My feathers love them. They are wide enough for them and they also use them for scratching their heads. Nails show a difference the same day! Highly recommend!
