Most 3‑prong poly folders include two interior pockets.
These prong folders are made from polypropylene (PP).
Prong poly folders commonly have glossy or polished covers and may feature bold printed graphics or other embellished finishes.
3‑prong poly folders are typically listed to hold up to 100 sheets.
Prong folders use three metal prongs (often listed as “3 prongs” or “three gold prongs”) to fasten and hold hole‑punched pages in place.
Poly prong folders are offered as single folders and in small multi‑packs; listings commonly show 1‑count and 2‑count packages.
Clear 3‑ring binder pockets are pre‑punched, single‑pocket sleeves designed to hold standard 8.5" x 11" sheets in a binder.
Capacities vary by type: binder sleeves list about 70 sheets, hole‑punch folders show around 75 sheets, and prong folders are listed to hold up to 100 sheets.
