GEEETECH Moisture Proof Vacuum Bag for 3D Printer Filament, Reusable Vacuum Sealed Bags to Protect PLA ABS PETG TPU, 40 x 40 mm Vacuum Bag (4pcs) + Vacuum Pump (1pcs)

Arrived very quickly and nicely packaged. Wound very neatly and with an extra bag in the box is always a nice touch.After printing on default settings it needed more fine-tuning but that's the be expected especially on a Bambu x1c. Sat lovely in the ams and with 0.4 nozzle it worked like a dream.After a few test prints I found printing at 175/180c worked the best for cleanliness and finish.While using the cold bed had to up the bed temp to 55c to get it to stick well.Yes it took some time and tuning but the filament looks fantastic and with a semi-rough finish you would expect from “wood” and I reckon looks pretty close to wood effect.I would recommend it but please allow time to tune for best results.

If like me you have a lot of half used spools of filament getting damp in a cupboard these bags are a must have. They’re so easy to use and the little vacuum device is great so much quieter than using a standard vacuum cleaner. The end result is an air tight bag to keep your filament dry.

All these kind of solutions are never perfect tbh.

Work great . Still a bit on the big side , but I can't find any smaller . At least it keeps the filament dry and dust free.

The bags are a good convenient size for either one near full roll or two near empty rolls, they're larger than the image made me think. Good seals, great to protect the filaments.The handheld vacuum pump died instantly. I put in brand new batteries, turned it on for a second just to check that it worked, but when I went to vacuum a bag it would no longer turn on. Slightly disappointed.

This item is the perfect way to store filament. Really easy to use and keeps the rolls air tight for future use. Would recommend to anyone looking to safely store filament.

I was hopeful about this, working on the basis that, even if the pump was as bad as reported in other reviews, I could use a manual pump as the valves are standardised - Right?Wrong! The standard valves are screw type, this one is a push to seal that doesn't work, it's too inflexible.The supplied 'pump' was *nowhere near* being up to the job, even with 3 new duracells. There's no manual pump available & other pumps I have don't match that poor push to seal valve. My return was started within an hour. Very disappointed!Sunlu is still the best option imho, their bags hold a single 1kg (wide) spool & the manually operated (screw on) pump will literally remove the air in 6 pump actions!.

these are so so thin... they work but you can get a hole in the bad so easily as, when its stretched from the suction it almost turns to cellophane. Throwing these out...

sac de bonne facture comparé aux concurrents. le plastique est assez épais et la pompe se visse directement sur le trou. ensuite on pompe 4/5 fois c'est fini. je suis contente de mon achat. seul bemol un peu cher le sac à l'unité

Ich habe schon andere Beutel mit primitiveren Ventilen getestet. Alles Mist.Hier schraubt man die Pumpe an, pumpt (wirklich flott) aus und verschraubt das Ventil.Kein sinnloses Gefummel, schnell und reibungslos.Die Beutel selbst sind sehr stabil.Einziger Nachteil den ich finden konnte: es gibt sie nur mit Pumpe.Uneingeschränkte Empfehlung!

Erster Eindruck: stabile, haltbare Folie. Luft herauspumpen, wenn die Pumpe richtig eingesteckt ist, sehr leicht und sehr schnell. Bin jetzt, nach erstmaliger Nutzung, sehr positiv überrascht. Kenne nämlich mittlerweile andere Produkte. Die funktionieren auch, aber nicht so einfach wie dieses.

J'ai commandé ces sachets pour pouvoir ranger à l'abri de l'humidité ambiante mes bobines de filaments entamées. Ils sont très pratique et d'excellentes qualités, la petite pompe électrique fait le vide d'air et garantie un stockage au sec. On retrouve la qualité de stockage comme à l'achat de la bobine. On peut même les remettre dans leur boîte d'origine pour un rangement optimal. Je recommande vivement.

C’est un bon produit, mais ce serait un super produit si tout les sachets ne se perçaient pas rapidement.Je vous rassure, seulement 2 sachets se sont percés (sur plus d’une quinzaine) et sur plus de 6 mois, mais c’est quand même embêtant quand on voit le prix…Je recommande mais il faut penser à vérifier les sachets assez souvent.
