Review on 💧 Advanced Moisture-Resistant Printer Filament: Humidity Control and Compression by Sean Patel

They are similar to other bags of the same type. I sealed the thread and left it overnight. The first picture shows the package right after sealing. The second photo shows the same bag after 24 hours. Without change. The package was perfectly sealed. I don't use a hand pump. It is difficult to use and requires a lot of energy. I bought a small pump that runs these bags. If you use them a lot, it's worth buying. To use these pouches effectively, make sure you have a hard, smooth surface to place them on. Make sure that the edge seal is completely closed. I run my finger along the edge of the seal and press it against the tabletop. Swipe back and forth a few times. Also, make sure the vacuum sealer is on a flat surface for best results.
