3D Printer Filament Storage Vacuum Kit- FugaCity 8Pack Reusable Vacuum Sealing Bags 35×50cm (13.8 ×19.7 inch), Dust Proof Humidity Resistant for Keeping Filaments Clean & Dry,8 Bags

Todo funcionó bien, solo que las bolsitas de silica vienen sueltas dentro de la caja y recojen humedad en el transporte, deberian venir dentro de una bolsa impermeable

Works better than I expected for the price, no complaints at all. Bags sealed well and the suction ports seem to be holding a good seal.

My last set of vacuum bags are no longer available, and I was misled by the reviews to believe that these would work. That was a mistake. Bags leak within a few hours, while the (Cobalt Chloride) indicators do not show humidity changes.The cost to return these to Amazon is now as expensive as the cost, so into the trash they go.

Seals good but after opening and vacuuming several times get wholes in bag from cracking.Had to throw away 2 bag so for.u get cracks in the bag and if you can't find the whole to put tape on it, want hold vacuum seal any more.

I was surprised to find nothing I could identify a s dessicant, just a single (1) weird chalk-like block. no instruction of how to use it. Do I break it into pieces? grind it up? eat it? So one strike for not providing a useable dessicant for each bag.Bags are generously sized (as you can see from the photo of 6 250g filament reels in a single bag.One of the bags at least will not hold a vacuum - I haven't tried them all yet.Pump is easy to use and works well.Overall, I guess better than nothing, but improved quality control and providing a good desiccant solution would have improved my score.

I have a lot of printer filament to store, and though most of it I tend to keep with desiccant in totes, there is the odd roll I don't have room for, or that I want extra secure. These bags seemed like a good solution to that stray roll problem, and so far... they've been doing okay. This kit comes with 8 bags, though haven't used all of them, a pump, humidity indicator sheets and little clips for ensuring the bag zips tight.All of it was remarkably easy to use, I just threw the roll in along with an indicator strip and used the clip to zip it up then sucked all the air out with the pump. The bag was very much sealed tight, practically factory level.Really my only gripes with the bags are that they're a little large for your standard 1kg rolls, and there is no good way really to store the extras. They're folded in a couple different ways to fit them in the box, making them somewhat inconvenient to pack neatly once you've opened it.Overall though, my issues with them are minor. They work great, and if you're just storing an extra roll or two they're a good option, especially if you're worried about any particularly humidity sensitive filament. You can throw some desiccant in the bag with the indicator and have a very low tech way to make sure your roll is safe between uses. Definitely a handy set of bags to have in my printer set up.

The media could not be loaded.  Our home has high humidity year-round so I keep my partial filament rolls in bags or bins to keep them dry. I needed a few more vacuum bags so I got this kit from FugaCity.It comes with 8 bags which are much bigger than needed for a single roll of filament. Each has a double seal and one-way valve. There's a small hand pump that threads to the valve opening to remove air from the bag. Once that's complete, a cap screws on to protect the valve. They work as expected and are holding their vacuum for several days.The bags are a little on the thin side. They also have a decorative grid pattern on the top, which looks good, but then makes it impossible to see what is in the bag. Also, the included desiccant packs were thrown loose in the box, so they are most likely worthless since they've had a chance to soak up moisture on their long journey to my home. The hand pump is a little fragile, but you could also use a vacuum cleaner in its place if needed.The kid includes humidity indicator cards which are helpful. There are also white plastic sealing clips that may help you press down the seals. I prefer to just use my fingers, though.These bags work well. If the desiccant packs were viable and the tops of the bags were clear, I would rate at 5 stars and highly recommend. But, not being able to see into the bags from the top is a nuisance and oversight on their part. The price is good and I will use them.

Box came with 8) ziplock bags, 8) clips for sealing the ziplocks, 8) humidity indicators, 1) vacuum pump and an oval block that I assume is a desiccant.The first two spools of filament I put in a single bag with an indicator. Sealed up just fine.The second bag I put a single spool of ABS filament but couldn’t get the bag to seal Evan after a couple of tries.The bags came folded across the ziplock edge. I think Fugacity Inc. should re-examine their packaging to mitigate this issue. I will try heating the bag a bit and try again.Dropped one star due to sealing issue.

Se rompen súper fácil, por el tipo de material que son le salen huecos.
