4 Ring Punchless Binders
This is the top of the punchless range and the trade-off does not change: the sheet is gripped rather than threaded, so nothing is perforated, and the mechanism takes less than a ring binder of the same spine width. Use it for the thickest sets of originals. Anything punched and heavy belongs in rings instead. See punchless binders, binders and document wallets.
