Filament Storage Box - 4 Pack 4L 3D Printer Filament Containers with 4 Hygrometers, Airtight Dry Boxes for Sealing and Protection, Water-Proof & Dust-Proof, Reusable Desiccant, Tube Cutter

【All-in-One Filament Storage Box Set】：4 pack filament storage box set for 3d printer filament storage. Each filament storage container holds one 1kg spool of PLA, PETG, ABS or ASA 3d printing filament. Set includes 4 filament storage boxes, 4 hygrometers, 8 reusable color-changing desiccant packs, 8 labels, 1 marker and 1 tube cutter to help you manage filament storage more easily. 【Innovative Airtight Design & Flexible Hygrometer Mounting】：Each 3d printer filament storage box uses a thick silicone gasket and secure latches to create an airtight, moisture-proof and dust-proof seal for filament storage. The hygrometer with double-sided tape can be stuck anywhere inside the filament storage container—on the lid, sides or bottom—so you can check humidity and filament condition without opening the storage box. 【Reusable Color-Changing Desiccant Packs, 8 x 50g】：Color-changing silica gel desiccant packs for storage absorb moisture inside each filament storage box to help keep 3d printing filament dry. The desiccant packs are reusable; when the beads change color you can regenerate them and put them back into the filament storage container next to the spool. Desiccant packs and silica gel work with your filament storage to reduce moisture problems during 3d printer filament storage. 【Pro Tube Cutter for Filament and PTFE Tube】：The tube cutter in this kit is designed for clean cuts on 1.75mm and 2.85mm filament and on PTFE tube for 1.75mm filament used in Bowden 3d printers. Smooth, flat cuts help reduce clogging and improve feeding from your filament storage box to the extruder. This tube cutter works as a simple choice for 3d printer tools and 3d printer accessories to pair with your filament storage box and other filament storage containers. 【Great Gift Choice & Fuitnerd Warranty Support】：This filament storage box set is also a practical gift choice for family, friends or colleagues who use 3d printing filament and 3d printers and need better filament storage. Fuitnerd provides a 1-year warranty and lifetime technical support; if you have any questions about the filament storage box or accessories in this kit, please feel free to contact us at any time.
