They close well, but you need to insist a little. They don't dry fast enough when washed. They are helpful and user-friendly!

Nice construction, they close well and seem like they can last a long time. They are easy to wash but they stain (I had them with carrots in the freezer and it has slightly left an orange color). For storage in the freezer, the larger ones are more worth it, the smaller ones are barely suitable for parsley, etc. Also, after freezing, they slide a lot from the moisture and are difficult to open, but they are very airtight.

Very good quality, thick, no comparison to the simple zip bags in supermarkets. They are definitely for many many uses.
You can easily wash them with a little water, depending of course on what you had put inside before. I mainly use them for snacks during work, any fruit and any dried nut.

Very nice and practical. Just like in the photo. You don't need to have disposable plastic ones. They can go in the fridge and freezer. I recommend them.
