Hifree 25 Pcs 3D Filament Vacuum Storage Bags Kit with Pump and Clips

Filament storage kit for 0.5 kg to 1 kg spools

The Hifree kit contains 25 reusable vacuum bags sized 32 by 34 cm (12.6 by 13.4 in). They accept 1.75 mm, 2.85 mm and 3 mm filaments in 0.5 kg, 0.75 kg and 1 kg spools. The bags suit PA, PC, PLA, ABS, TPU, ASA, PETG and other common materials. Each bag uses a black and transparent dual-sided design that blocks light on one side while letting you inspect the spool through the other.

USB pump and sealing clips change daily workflow

One USB-powered vacuum pump draws air from the valve in about 12 seconds and stops automatically. It runs from any USB port, including power banks and laptops, so no mains adapter is needed. Five sealing clips lock the bag opening before evacuation, creating a repeatable seal that resists punctures thanks to the thick PA+PE composite film. The kit replaces single-use desiccant packs with a reusable humidity barrier.

Simple three-step sealing, watch for clip alignment

Press the valve flat, align the pump nozzle, then hold for 12 seconds until the pump halts. The process is quick, but the clip must sit squarely across the full width of the bag or air will leak back in. Overfilling a bag above the spool height can also prevent the valve from seating properly. Users who skip the flat-valve step often blame the pump when the seal fails.
