When the 3D printer filament is exposed to damp air for a long time, it becomes brittle and then causes printing failure, such as the model has a lot of strings, has a rough surface, or is whitish. Kywoo 3D printer filament vacuum bag is a great way to solve this problem by keeping the filament in vacuum storage when you're not using it. It helps keep the filament dry, dust-proof, and greatly improving print quality. And can be reused many times.

Note: When the desiccant encounters a certain humidity, its color will change from purple to red, so as to help users clearly know the filament dryness.
