Ring binders

A ring binder is slimmer and lighter than a lever arch file – good for training materials, price lists and manuals. The subcategories are split by the number of rings: a two-ring binder takes sheets with standard two-hole punching, while a four-ring binder holds sheets more firmly and keeps them straighter. Spines run from the 1.5 cm College binder to the 7 and 8 cm Panta Plast binders with D-rings. Transparent models come from Viquel and Deli.
