    I bought a couple of these several months ago and have been waiting for Biome to get some more back in stock, as I intent to buy several more. These containers are incredibly useful because they can go in both the freezer and the oven. Great for freezing batches of leftover soups, stew etc, as well as being a really good size for storing baked goods.
