ZENO Cereal Storage Containers 4 PCS | Cereal Containers Dishwasher Safe | Storage for Cereal, Pasta, Rice & Dry Foods | Airtight Food Storage Container | Holds 4 Litres

I bought these for mum as her old ones weren't air tight. These were good value, and replaced her various sized/shaped ones with a nice uniform set. She seems pleased with them, and reports that they were good value for money.

Perfect for 3d Printer filament.

First Impressions & Context While these are technically designed for cereal, I bought this 4-piece set for a completely unconventional use: storing my 1kg 3D printer filament spools. After drying out my filament in a heater, I need somewhere truly reliable to keep it moisture-free until I am ready to print. These containers turned out to be the absolute perfect dimensions. I can confirm that both SUNLU and Creality 1kg spools fit perfectly inside, and they should be fine for most other standard brands too. Performance & Real-World Testing The airtight performance on these is honestly incredible. I drop a 1kg spool inside along with a desiccant bag and a little digital hygrometer, clip the four latches shut, and store it away. To give an idea of how well they seal, I have had a few spools locked away in these since around Christmas. Months later, the hygrometer inside is still reading a bone-dry 10% humidity, and my colour-changing desiccant beads are still bright orange, proving that no ambient air is leaking in. They do a far better job than standard vacuum bags which inevitably leak over time. My only minor complaint is that I wish they were a bit cheaper so I could afford to buy a set for my entire filament collection! The Bottom Line If you are a 3D printer user looking for a robust, stackable, and genuinely airtight dry-box solution, these are fantastic value for money. They completely solve the issue of filament hydration, seal flawlessly for months on end, and are highly recommended.

Having tried a few of these over the years, these are one of the easiest to fill, the tabs make a refreshing break from having to tear open a clip sealed one. The "spout" opening is easy to open too, however, it would have been nicer having it a bit closer to the edge so you could properly empty it when you get to the last bits. They appear suitably air/water tight so should keep your food fresh for some time.

Food stayed really fresh in these. Good tight seals. Used for cereal and for dried fruits.

Good quality

Very good quality, as per the expectation. Value worth.Highly recommend.

Smaller bottom than top. They are really big and take up a lot of room. They do seem to keep cereals etc fresh and it is good that you can open the small door to pour. I would have preferred a shape which did not seems so 'gappy' when they are next to each other on the cupboard shelf.
