It wasn't completely air tight. Crackers would still go stale, just not as quickly as leaving them out. Most containers were ok. One of the six I purchased broke at the handle. I only carried these by the side. For the most part, a good purchase 5/6 isn't so bad. Now I have to replace a single container and I don't think they are sold that way.I wanted to organize my pantry and bought these canisters. They are simply but elevated the overall look. I always wash containers before use, and noticed the lid filled up with water. It took a lot of shaking and leaning this way and that to drain all of the water. I am not sure how this will affect the air tightness and keep out moisture. I'll have to wait and see. (Follow up). The next day the sugar is dry! I love the lid design as wellThe product arrived very quickly - on a weekend I wanted to tidy the pantry. These are great! Airtight and easy to grab with one hand. The tops open easily with one hand as well. Wish that they were slightly bigger as they don't quite accommodate 5lb bag of flour. As I rarely have a full bag of flour - this isn't really a huge issue- just used the leftover couple of cups and baked something. Problem solved. Several weeks into having these I am still very pleased with the item and purchase. Recommend!We bought these so we'd have a place to store snacks on our countertop, and they're even nicer than we anticipated. They're just the right size. They're stackable. They seal tightly, yet they're so easy to open and close that you can do it with one hand. If you're looking for attractive, functional food storage containers, you'll love these!These containers are exactly as advertised. They are of sleek, smart design, very airtight and absolutely leakproof. I especially like the one finger opening of the tops, and they’re interchangeable with any bottom. They are a nice compliment to my kitchen. Thank you!!I’d give an A (1st pic) : for helping me to organize my supplements! I buy in bulk because I like to tailor my workout supplements to meet my individual needs. Love how these cleaned up the many bags I had cluttering the cabinet. I’ll give a B : for not having printed instructions sheet for caring for the containers. Instead they are on the printed inserts with the fake jar “contents”. These get B- : the lids aren’t dishwasher safe and can only be wiped down. Not a deal breaker though.They earn a C (2nd pic) : for not being scratch resistant AT ALL with the plastic seaming a little on the brittle side. The scratches were a result of me GENTLY mixing the powder with a stainless steel fork. I was intentional about being gentle and barely grazed the inside of the containers. Moving forward I will take the “grit” of the powder and the material of the utensil I use to mix it with into consideration.And lastly a D (pics 3 and 4) : for quality control allowing a bad edge seem go through which creates a bad seal. This happened to 2 of the 6 that came in the box. There are some rants regarding this issue and I agree with them. There are some reviews that are 5 stars and the reviewers love these and you can see this issue in their pics hopefully they don’t find out the hard way the seal is no good!The overall 4 stars is because I like the price point and overall function. Will be reaching out to the manufacturer about the seal issue which may change my overall rating one way or the other ; )I have these all over our house with dog treats. By the doors, in my daughter's room, by my chair in the family room. It's just great to open a big bag of treats, divide them up and be able to have them readily available for my dogs when we're training or just rewarding them. Because they're easy to open and close, it's safer for not having dogs get into the treats. Just don't forget to close the lid. I did that once. Lesson learned.Perfect size. Look great! BUT when you wash them upon arrival you have to work hard to get all the water out of the lid.The 4 items arrived rapidly, were packed well in the original box with simply a label stuck to it. So not in Amazon packaging that hid contents. Not a problem. The storage boxes are excellent quality and the lid/seals excellent. I haven't filled them yet but intend to store flours in them. From a height perspective they almost fill the shelf height in my standard kitchen cabinet larder cupboard, there is not much room on top. I have washed them (don't submerge the lids in water). and it's easy to get your hands inside to wash and dry. Due to the overall size, they would be difficult to grip with one hand if filled with heavy contents like flour. This is the second set of this brand / style I have purchased, the earlier one was a mixed size set. I was so impressed with the earlier set, that I purchased these larger containers.I have used these for laundry, stock pots and stock cubes. Came quickly, good quality and solid sealing lid. Nice stickers with white pen. Stack really well.Look good, the rocker latch on the lid is super quick and convenient to use, they clean up well and seal well for dry foods too. Bit pricey but I bought some cheaper ones and regretted it… these you can display on the countertop rather than hide away in a cupboard in disgrace :) Perfect for cereals, dog biscuits, etc.The containers fit into my cupboard really well. I managed to stack them on top of each other and save a lot of space for other things and they're very easy to clean.They look nice, but instead of being straight, they taper a bit at the bottom which effects what you can store in it. It's fine if you are going to empty the contents of a packet strait into it, but if you want to keep anything in the packet, the shape effects what fits. It holds the contents of a 750g box of cereal with a bit of room to spare.
