Review on TOGGLER Toggle Hollow Door Polypropylene Fastener by Matthew Sutton

My local hardware store didn't have lever anchors for hollow doors. (They have other solutions that don't look as reliable). So I waited weeks to get them from Revain but they are exactly what I wanted and work great. I've attached several shelves to the door and they seem sturdy. Maybe it's just me, but I find it odd that they sell them in odd numbers (5) per pack?
