Highly recommended to keep filaments in perfect condition

If filament is exposed to damp air for a long time, it can become brittle and result in poor printing performance (and rather interesting sounds during printing)

A vacuum bag is a great way to solve this problem, particularly if you need to store your open filament for any length of time.

Perfect for keeping all filaments moisture-free and dust, especially PETG that suffers from moisture absorption. Its use is very simple and perfectly seals in the bag.
