Effective sealing to protect filaments from dust and humidity. Dual sealing rings plus a moistureresistant strip work together to keep the interior dry and clean, preserving material quality. Easy to use design for reliable storage. A rotation mechanism and a sixlatch lid provide secure, convenient access and storage. Realtime monitoring for simple oversight. The builtin electronic display shows temperature and humidity levels so you can monitor conditions at a glance. Broad spool compatibility with easy feeding. Holds 1 kg spools with thickness from 52 mm to 70 mm and up to 205 mm in diameter, with pneumatic connectors for easy feeding. Use scenarios Home workshop or makerspace: store and condition 1 kg filament spools before printing to minimize moisturerelated issues and improve print quality. Small business or classroom: securely store multiple spools with accurate humidity and temperature monitoring to ensure consistent material performance. Longterm storage: keep hygroscopic filaments in a controlled environment when not in use to reduce moisture uptake and degradation.
