Warm Tips:
1. The larger the metal ring, the easier it is to insert the spine's assortment of clear inserts.
2. The sheet capacity is based on the thickness of common paper. Please understand that different paper thicknesses do not allow for the same amount of paper to fit in the metal binder.
3. our usually said “xx inch binder", ”xx inch” refers to the size of the metal ring, not the size of the spine (product width). For example, the “1 inch” in “1 Inch binder” refers to the diameter or vertical height of the metal ring.
