SUNLU3D Printer Filament Vacuum Storage Kits,8 PCS Filament Storage Bags for 3D Printer Filament, Remove Moisture from Damp Filaments, Spool Storage Sealing Bags Kits, 32 * 34CM(12.59 * 13.38inch)

Does what I expected and easy to use

I love these bags. It feels solid and they all sealed great. Time will tell if it holds, but the bags look like they are made well. The most impressive part to me was the vacuum pump. I thought it was going to be a joke, but it is legit. The hand pump was faster than my electric one. The kit has everything you need to seal your filament. I am definitely buying more of these.

Using on normal sized spools commonly used results in what you'd want and expect. It seals it in perfectly, and it has remained sealed for about a month or two with no signs of a 'leak'. Problem is, when I try to use a smaller than normal spool (such as the small pla spools that usually come with creality printers) the bag just doesn't remain sealed, as if there is a hole on it somewhere.

Easy to use and perfect size for 1kg roll of filament keeps my tote “looking” organized! Love how much air it actually gets out of the bags I was actually surprised! Would recommend to anyone that has or will have a good amount of filament

***UPDATE*** Got some PETG filament and decided to use the "bad" bag only for it to work sealing my ABS filament. Having a few spools of filament now, I was able to use all 8 bags and they sealed. The other 5 I used earlier is keeping a tight vacuum seal, so I'm super satisfied with this kit. I'll be buying another if I need more bags. Changing my rating from 3 stars to 5 because everything worked as needed.Original Review:When the bags seal it works: I have multiple smaller spools of PLA filament that I use for multiple prints, and I rewrap those smaller spools so that no added moisture gets to them. I can fit two of the smaller spools inside one bag, which is an absolute plus. The kit works exactly as it needs to be......the issue I have is that one of the eight bags do not seal (so far). Granted, I've only used 4 of the 8 bags--but now there's only 7 usable bags instead of 8. That's not giving me the value for my money. If another bag doesn't seal, then 25% of the product doesn't work. There should be some quality control that ensures that every bag seals.

The bags seal OK and the vacuum pump is easy to use. The only down side is the plastic seal assist tabs fall off easily and are easily lost. You can still seal the bags by hand.

I bought these for my husband to store his 3D printer filament reels. Because of the price, I wasn't expecting a lot but figured it's better than leaving them out in the open air. My husband loves these bags. Not only do they work fantastic, but they are perfect for spaces with small storage available. The empty bags are easily stored until needed and they aren't like the dehumidification boxes that are bulky and expensive.

I like the idea, and would have been completely happy with it, except that 2 out of 8 bags leak on day 1 and don't sealwe'll see how long the rest keep a vacuum.getting 75% of what you pay for, doesn't feel good. If the rest don't keep a vacuum for at least a week, I'll return them all and try something else

Muy buenos, me gustaría que mejoraran un poco el tamaño (más grandes) ya que apenas si entro mi carrete de filamento, cumplen totalmente con su función

Pratico, ben funzionante e c'è l'essenziale, ci sono molti più sacchetti di quanto si possa aver bisogno nell'immediato, nella scatola c'è tutto l'occorrente.ConsigliatoLH

funktioniert tadellos. Vakuum wird sauber gezogen. Das wieder öffnen funktioniert auch prima. Spulen sind vor Feuchtigkeit geschützt! Bin zufrieden!

J'utilisais une machine sous vide de cuisine pour préserver mes filaments.Avec ce kit, réutilisable, c'est encore plus simple, et surtout plus rapide. En 4 à 5 coup de pompe, le vide est fait complètement. L'opération prend moins de deux minutes.Les sacs sont plus épais que des sac congélation. Ils disposent chacun d'une pince pour refermer le sachet.

Las bolsas van bien para las bobinas de 1 kg y hace bien el vacio.
