I’ve tried many types of silicone bags, including Stasher and Luumi, and these are definitely my favorite. Stasher doesn’t seal well and are hard to get clean with all the seams, and my roommates and I found the Luumis too complicated to use regularly. These however are more affordable and work much better than the other brands. The closure is plastic, which I do try to avoid buying, but I think it’s worth it for this product.
Very sturdy, washes easily. Being new, the slider bar was a tad sticky on the silicone, but I was able to get it off and it slides easily every use now. GREAT product, and it reduces my carbon footprint!
