Reviews for this product were varied, but I decided to give it a go. A wise choice. These arrived on time, in a plastic bag, in a box, inside a sturdier box…in perfect condition. They are very sturdy compared to most I’ve seen. I used them in preparing a meal for a family who lost a loved one. If they easily accommodate 5 lbs of potato salad, I’d say they’re sturdy. I also used them for sliders, and a couple of fruit trays.
