The eSUN eVacuum Kit is specifically designed for sealed vacuum storage of 3D printer filament.
Damp 3D printer filament can lead to filament buildup, clogging, poor adhesion and other adverse effects.
Seals, protects and thus extends the life of filaments.

-Dustproof and moisture-proof: double seal and single side embossing treatment, high performance valve, good sealing performance, easy to pump out. Microporous vacuum storage bag allows maximum air removal, protect your filaments from moisture and dirt.
 
-Monitor the moisture of the filaments: The humidity monitoring card turns from brown to light blue in a high humidity Environment, making it easy to monitor humidity. Transparent vacuum bags allow you to quickly see the moisture content of your filaments without having to open the bags.

-Easy to use: Simply place your filament in a vacuum storage bag, close the cap with the locking clip, hold the outlet on a flat platform, and then suck out the air with the pump. (We recommend to push out some air first before pumping manually, it will make it easier to pump out and save time and effort).

-Broad application: can not only be used to store 3D printer filaments, but also can be used to store candy, coffee beans, dried flowers, baked goods, dried fruits, cookies, tea, nuts, etc.
