1Prevent Oxidation: All 3D printer consumables are known to absorb water from the gas, which can cause oxidation of the consumables, leading to straining, clogging and poor adhesion. Our bags use a vacuum double sealed to completely remove all gas and prevent any water from affecting your 3D prints. 2Ideal Storage Flexibility: Our vacuum bags can hold up to 2 reels in 1 bag or just 1 reel in 1 bag, giving you the flexibility to store the filament of your choice. 3Comes with A Hand Pump: Our vacuum sealed bag kits can be used with any conventional vacuum cleaner to remove gas. That said, all of our bags include a free hand pump that allows you to expel gas. 4High Compatibility: This 3D vacuum bag is designed for 3D printer consumables and is compatible with all 0.5kg, 0.75kg, 1kg, 2kg reel consumables and 1.75mm, 2.85mm, 3mm consumables. 5Applicable Scenarios: This vacuum bag can be used not only for 3D printers, but also for storing food, pet supplies, clothes and other materials.
