Creality Official 3D Printer Vacuum Storage Bags, 12 Transparent Sealed Bags Dust Proof Humidity Resistant Keeping Filament Dry, 35 x 35CM Reusable

I bought these items as they had the Creality name to them. I have been looking for quite a while for reusable vacuum bags for my opened filament storage to prevent moisture from getting to it. When the box arrived I opened it and saw that the bags seemed to be the same as similar ones I have experimented with in the past used for clothes storage. I thought that as they seemed to be endorsed by Creality then these vacuum bags must be of a better quality. So as a test I sealed up 4 random rolls of used filament. After 3 days I checked them and all seemed to be well. I decided to order another box of bags. Five days later I looked at the test bags and all had lost their vacuum. I then then thoroughly checked each filament roll for any sharp edges or possible sticking out parts and they were all good. I tried to reseal the 4 rolls again and 3 of the bags would not hold a vacuum. I checked the press seals on all of them to make sure the properly closed and then tried again but they would not hold a vacuum. The forth one did but at £21 for 12 bags this is an unacceptable failure rate of 75%. The fact is these are the same type of vacuum bag that you can get from B&Q or other similar places. Creality I can only assume did very little testing but obviously got these bags at a good price, repackaged them, put their name on them to make you think they worked and now sell them for a handsome profit!!!!! To be honest I have no problem paying a bit more if they work. The name Creality on the box gave me a, in this case, a misguided assurance of quality and an item that would work every time. This has not been the case. Purchase at your own risk.

1 out of 2 of these don’t hold a seal at all. Avoid. Once you vacuum and seal about 30mins later it’s pull air bag in. Not what you want for a vacuum bag. Also the large cap on the side makes hard to store filament side by side

Misleading photo showing two reels in the bags. These cannot hold two Sunlu reels like the "currently unavailable" bags I previous purchased from Creality. Also found 2 of the bags leak the vacuum after 2 days!! Not recommended for these reasons.

Die Taschen halten perfekt dicht, man muß nur bei den ersten Verwendungen die beiden Dichtstreifen mit der Hand nachdrücken damit sie richtig schließen, das mit der Klammer klappt sonst nicht (außer man viel Kraft)

A enfin des sacs résistants pour mettre les bobines de filament sous vide enfin un sac avec une buse en plastique dur qui permet de recevoir le petit aspirateur et qui fonctionne parfaitement. La petite pompe sous vide fonctionne à merveille alors que sur une autre version c'était quasiment impossible

fallan mucho por su balbula escasa de membrana de goma, yo las deseche por ese motivo, aunque no las tiro para ver si puedo implamtar unas membranas de goma de silicona fina mas grande, entonces si las utilizare.

Werden undicht und der Support von Creality konnte mir auch nicht weiterhelfen, nie wieder irgendwas von Creality.

I'm satisfied with the seller. Good product quality and quick shipment.
