Cereal Containers Storage Set (4L / 135.2oz), 4PCS Airtight Food Storage Containers with Lids, Cereal Dispensers for Kitchen Pantry Organization and Storage with Pour Spout, 20 Labels, Marker

High quality containers. They seal tight keeping products fresh. Easy to open and close. Definitely a great product for the price.

I purchased two sets of these for my godson for Christmas. He wanted them to store his rolls of filament. He used one per roll, which fit perfectly. The clear container allows him to easily see the colors, as well as the temperature/humidity reading from the meter inside each one. The top seals on pretty tight to prevent moisture from getting in. He was so excited when he opened his present. That night, he organized all of his filament and set the containers up in his closet. I'd say it works pretty well for filament storage. He has not had to recharge his dessicant yet and it's been a month of use.

Great containers! Pour spouts are the perfect size for cereals, etc.

We use these storage boxes on our 3d printer projects (Bambu and Qidi) to store open and partially used fillament as longer term storage. They work well and seal very good to keep humidity out. We always look for well priced quality additions for our printing needs and always end up on Amazon. Highly recommended!

A pain trying to get open and shut

These are really nice and convenient. I’ve actually bought two sets, one for my counter and one for my son’s dorm. They’re perfect for cereal, rice or small pasta and give a much more organized appearance. They are also dishwasher safe which is convenient because they do need to be cleaned between products.

A 1KG filament wheel fits with a little wiggle room on all sides, and the seal is airtight! Very affordable for organizing small to moderate collections, and the cereal pour spout doesn't affect stacking. Only downsides are the locking clasps are a little weak (I had to relock the fresh plastic a few times at first to get it to stay locked), and you can only order 5 at a time which is a minor inconvenience for me (I wanted to order 10 and store my entire filament supply).

I use these rather unconventionally, as air-locking storage for hygroscopic 3D printing filaments, and they’re wonderful! They’re very sturdy, rather stackable, and most importantly keep moisture out! This pack also came with a couple of different funnels and a measuring cup! My only complaint is they’re a little tough to initially pull apart because they’re stacked and that creates a vacuum, but I won’t deduct any stars for that.
