Extra-tough poly pockets outperform regular paper pockets for binders and will not fray or tear out of rings. Each letter-size divider is double-sided and has two pockets that each hold 20 sheets. Multicolored design allows easy reference. Translucent divider pages are made from transfer-safe poly so they will not damage photos or transfer ink or toner. PVC-free poly material will not stick to materials inside.
