Sovol Filament Storage Bags Kit with Automatic Vacuum Pump

These do a good job of vacuum sealing my 3D printing filaments. I vacuum seal ALL of my filaments to help preserve them. This unit pulls a better vacuum than some of the factory packaging. I actually have to stop early to make sure I don't warp the Bambu Spools. I only deducted a single star because it isn't wireless and battery operated.
