This 3D printing filament vacuum seal set includes 30 storage bags and a powerful manual air pumping, providing an organized way to store multiple spools while damage and filament degradation. Feature PA+PE composite bags, ensuring sealing that maintains freshness for over 30 days, keeping filaments dry and ready for printing. Enables faster air extraction with the included manual pumping, allowing users to efficiently preserve 1.75mm, 2.85mm, and 3mm filaments including PETG. Place the filament spool inside the bag, seal it with the clamp, then use pumping to remove air—ensuring stay flat during operational for protective against humidity. Designed to fit standard 1kg spools, this storage works with various 3D printing materials, making it ideal for hobbyists, professional, and educators needing filament preservation.
