3D Printer Filament Vacuum Storage Bags Kit with Electric Pump

These are a lifesaver! They fit my Bambu Filament and Hatchbox Filament perfectly with some room to spare. I love that it also comes with the mesh bags and beads to help control the humidity. Even better, the beads will turn green to help you know it is time to trade them out. These are strong containers and were easy to unpack and to put everything inside. I like that the top is airtight to keep your filament safe. Will be ordering more.

These filament storage boxes are very useful and easy to use. They help keep my filament spools protected, dry, and organized. The set of four is perfect for my 3D printing setup, and the boxes are a good size for the spools. I’m very happy with this purchase!

Good bins, good desiccant, good value. The bins are a bit flimsy which makes it somewhat difficult to align the lids, but for occasional use they are absolutely sufficient for the purpose.

These work great for my Bambu labs filament. I drop the filament in with some silica and a hygrometer to measure humidity and I've never really had an issue. I do check them from time to time and refresh the silica, but these are the perfect size and they store well.

Airtight cereal boxes that a regular size filament roll fit in perfectly

These the perfect size! Took me a while to find these. All the other filament containers were too tall to fit my shelf system (max 10" high). Great quality product--solid and tight seal. And it comes with its own dessicant. There was a slight issue when received, but I contacted the seller and they promptly replied to corrected the problem. Service is fast and excellent.

These storage boxes are essentially cereal / dry goods containers that are the proper size for the intended purpose. They even have a top opening to pour cereal out of. What's nice is that they include the color-changing desiccant in sufficient quantity that it should rapidly dry the filament and keep it that way. About 1/3 bottle per dry bag - also included. Excellent material should last a good while.A couple issues: Labels are not properly die-cut on the sheet I got, so I have yet to use them. The seal around the top is tricky and can be frustrating to get it aligned right so it seals. But generally they seal very well with the four wing snaps. The two end snaps have one latching point each, and the sides have two each. Not sure what good the top opening is, and the latch handle catches on the upper shelf in my setup.Because of the height of the container the walls are tapered out at the top, and with the added width of the top snaps, the containers are not too efficient using shelf space. I have one filament reel that is a very tight fit. The reels from other various suppliers fit fine.Overall I think the containers are a good value for the money, especially since it gives you everything needed to set up six drying boxes. I knocked off one star for the width issue and the finicky seal.

Was very surprised at the value I received. Not only are there good quality plastic containers that are sized perfectly for a typical 1KG roll of filament, but there's room for adding a desiccant basket and/or roller function at the bottom.It was particularly helpful that these came with two half-kilogram of color-changing orange desiccant, for a total of 1KG of desiccant in sealed, resealable bottles. And they do appear to have good sealing around the container AND on the very large pouring hole. But speaking of a very large pouring hole.....These aren't perfect, and there's room for improvement, but I suspect that these are repurposed dry bulk containers judging by that big hole in the lid. Since a foreseeable use of these is to feed filament directly from the container, having a much smaller hole to pass through the filament would be ideal; something like a silicone straw hole would work well. Still, it will work fine passing through the large hole even though it does open it to the atmosphere more than I'd like. The labels are not erasable, and a bit meh, but they work fine for permanent labels. Nothing pretty, but that doesn't detract from their value in my opinion.None of these limitations warrant reducing the star count, as this purchase definitely still exceeded expectations.
