Most black staplers in this selection staple about 20 sheets for many desktop/handheld models and up to 40 sheets for heavier handheld or full-strip designs—typically about 20–40 sheets.
Black staplers are typically made from steel or other metal and from plastic.
Long-reach models provide extended reach (a listed example is 12 inches) for centerline or booklet stapling, adjustable paper guides for placement, dual‑clinch options for permanent or temporary stapling, No‑Jam technology, and non‑skid feet for stability.
The listings reference 1/4‑inch and 5/16‑inch staples. One description shows 1/4‑inch staples used for roughly 2–25 sheets and 5/16‑inch staples used for roughly 2–40 sheets.
Common ergonomic features include soft or contoured grips, ergonomic comfort‑grip designs, and stand‑up or handheld shapes intended to improve comfort and control during stapling.
