Product overview
What You're Actually Getting
The Charles Leonard 4R-BP is a straightforward two-hole paper fastener: a brass-plated round head about 10mm across, a 1-inch shank with a sharp point for pushing through pre-punched paper, and two flexible prongs that fold flat on the back side. It ships 100 to a box. Charles Leonard's own listing describes rigid shanks and sharp points for easy penetration and wide heads sized to keep the fastener from pulling back through the hole — standard claims for this fastener category, not unique engineering.
Charles Leonard Inc. sells primarily into the school and office supply channel rather than as a marketplace-only brand — the same 4R-BP item turns up on education-focused resellers like DK Classroom Outlet and The Knowledge Tree, not just Amazon. That distribution pattern is a mild positive signal: it suggests an established supply-catalog product rather than a here-today reseller listing, though it isn't proof of superior manufacturing.
On evidence quality: there is no independent lab test, tension test, or third-party durability review of this fastener anywhere we could find — nor would we expect one, since round-head paper fasteners aren't a category anyone benchmarks. The only real-world signal is the Amazon listing itself, which currently shows a strong 4.7-out-of-5 average across roughly 800+ ratings. That's a good aggregate number, but star ratings on a $5 box of fasteners mostly tell you the product does the basic job it claims, not that it beats close substitutes.
One honest gap worth flagging: Charles Leonard sells this exact-looking fastener in at least six shank lengths (1R-BP through 6R-BP, roughly 3/8 inch up to 1.5 inches), and the thumbnail images across those listings look nearly identical. Buyers who don't check the shank-length code carefully can end up with a fastener too short for their paper stack. Also, "brass plated" means a plated finish over a base metal, not solid brass — worth knowing if you need true non-ferrous brass for a specific craft or corrosion-sensitive use.
Bottom line: for routine binding of light-to-moderate paper stacks in an office, classroom, or basic craft project, this is a safe, well-reviewed commodity choice. It is not a heavy-duty or archival-grade fastener, and no claim to that effect should be assumed from the brass-plated finish alone.
