SORRY NOT ABLE TO FILL ORDERS AT THE MOMENT THANKS FOR YOUR PATIENCE.
This is how papers were secured before metal staplers...
Bump paper fastener creates a beautifully trim connection between pages.
It works but is a little stiff so take care, the punch makes a hole, a slit and a tab which it then automatically threads through the slit... very dextrous manoeuvre for a handheld machine
Patented in 1914, Bump Paper Fasteners from La Crosse Wisconsin, this shiny metal version is pre-1942.
Used but working order
