Review on Prefer Pets Weight Carrier Chocolate by Eric Render

We bought this soft side carrier to take our 6 lb kitten on a short flight. It is airline approved and fits perfectly under the seat in front of you. It has adequate ventilation and is easy to carry. My only issue with this holder is that there are no clear instructions on how to use the two curved ends that give it the rigidity it needs. After a long search and a closer look, we found a way to insert parts. Some simple pointers would be helpful.
