Eco-Friendly Premium Customizable View Cover: SKYDUE 1.5 inch 3 ring binder—your ideal back-to-school essential. Made with high-grade PVC , it is 100% BPA‑free, non-toxic, and meets strict U.S. safety standards. Fully ventilated before packaging to reduce odors, while the customizable clear cover lets you personalize it for school or daily use.
Heavy-Duty Durability Built: Built to outlast standard ring binders with reinforced heat-pressed edges that resist cracking and splitting. The 0.1inch thick cardboard core keeps the ring binder rigid and warp-free, while the flexible PVC material withstands scratches, daily wear, and constant use.
Large Capacity: 1.5 inch D-ring design holds up to 450 sheets of 16 lb 8.5" x 11" paper. Pages lie flat and organized, perfect for loose-leaf textbooks, notes, homework, and assignments—ideal for heavy classroom use.
Smooth Page Turning & No-Slip Secure Ring Mechanism: Upgraded silver D-rings close tightly to prevent paper from slipping or tearing. A thick cardboard pad under the rings eliminates cover indentations. The reinforced mechanism ensures smooth page turning even when full. A 4.7inch tall inner pocket provides extra storage for loose papers and supplies.
