Winrock Reusable Silicone Food Storage Bag, for Microwave, Oven, Fridge, Freezer & Sous Vide Zip Sealed Containers (2 Large size 51oz 1500ml)

High quality, stands up on their own. Very easy but affective closure. Thick and no scent. Perfect. I'm buying more. They are just smaller than I expected.

High quality, very reusable, excellent insulation, easy to wash.

I've purchased another more expensive brand of silicone storage bags and find this brand just as effective and much more affordable. Some reviews indicate these bags are more difficult to open or close, but that's not been my experience. It does take a bit of force, but if these were quickly and easily opened, they might not reliably stay closed. This might be an issue for anyone with arthritis or similar issues. I am sixty and have no problem opening or closing these. No problem cleaning either. I spray these with Dawn dishwasher foam, let them soak a bit, scrub out quickly and then put upside down into the dishwasher (held open by top rack prongs). This cleaning method seems most effective for removing grease and odor. I haven't used these for any soups or other foods that could stain as I prefer glasslock containers for those. To dry these, I use spring clothespins to attach (open) to a clothes drying rack. There are also products on Amazon to hold plastic bags open for filling; I have a couple of these and they would also help with drying. These bags work well for cheese, nuts, veggie sticks or dips, butter, and other similar foods. I have not used these for cookies or muffins. These pass the pinch test, so presumably they are 100% silicone. Will purchase these again as needed, though no signs of wear yet. Great for packing lunches/snacks for any excursions (cycling or traveling for us). Highly recommend!

Le silicone est assez épais pour se prêter à la cuisson sous-vide dans un récipient d’eau. je m’en sers également pour ranger au frigo légumes, reste d’un repas. La fermeture est efficace. Excellent A-1

Exactly what I wanted, great silicone reusable bags, thick and durable, I plan on using them to store things for snacks/sides in a packed lunch but they're supposed to be temperature tolerant as well which is a bonus
