Give up the plastic storage bags and switch to reusable, all-purpose Stasher bags. They're made of pure platinum silicone, meaning there are no fillers or by-products and are as pure as glass. Durable, non-toxic, BPA and BPS free, hypoallergenic, and temperature resistant. Use these bags in the microwave, for freezer and fridge storage, in the oven, on the stovetop - they're great for sous vide, and they're dishwasher safe! You can even write on them! Sandwich size 7.5" x 7.5" x 1" / 15 fluid oz.
