Filament Storage Box, 3D Printer Filament Container for Sealing and Protection, Clear Storage for Home & Office 3D Printing, Water-Proof and Dust-Proof Box for 1KG Spool (4 PCS)

["AIRTIGHT & MOISTURE-PROOF SEAL — Stop Stringing, Brittle Prints & Filament Waste: PLA can degrade in 2–4 weeks of open shelf exposure; PETG, Nylon and TPU absorb humid air even faster. Each filament storage container features a food-grade silicone sealing ring plus four reinforced locking buckles for a verified airtight, water-proof and dust-proof seal — drop a hygrometer with desiccant inside and watch internal RH stay under 15%. Your spools stay factory-fresh from week 1 through week 52.","4-BUCKLE SECURE LOCK — Engineered Around the #1 Complaint in This Category: The most common reason makers return cheap filament dry boxes is lids that pop open or silicone seals that leak after a few cycles. Our four reinforced side buckles audibly click on all four edges so the lid sits flush every time, even after hundreds of openings. Built from impact-resistant PP-grade plastic for daily workshop use, not occasional hobby storage.","UNIVERSAL 1KG SPOOL FIT — 5.5L Interior, External 8.31\" × 4.4\" × 9.25\": Precision-engineered for the industry-standard 1KG / 2.2lb filament spool used by virtually every brand — accepts spools up to ⌀200mm × W75mm. Compatible with 1.75mm and 2.85mm PLA, PLA+, PETG, ABS, ASA, TPU, PVA, Nylon, Silk, Wood-fill and Carbon-Fiber composite filament. Crystal-clear transparent body lets you check color, material type and remaining filament at a glance — no need to break the seal.","STACKABLE SPACE-SAVING DESIGN — Reclaim Your Print Bench in Minutes: Flat lid + recessed base let boxes nest securely into a tidy vertical wall on any shelf, workbench or rolling cart. Ergonomic side grooves give a secure one-handed grip even from high shelves. Perfect for the home maker switching colors mid-project, the classroom managing student materials, the makerspace, or the small print farm rotating PETG and PLA jobs. Goodbye tangled spools and dusty open racks.","4-BOX STARTER KIT — Perfect for New Makers & Single-Material Workflows: 4 identical clear sealing containers — ideal if you print mostly PLA in 3–5 favorite colors, or want to try our system before scaling up.
