Inconceivably

simple: Take one or two of the contiguous staple league from the nondescript cardboard and puts them in the free space of a matching stitching machines. One then presses the triggering arm of the machine, the clip is forced through the material to be stitched and can be fixed in two different ways there.
The 8 bracket is intended for stronger paper stack, otherwise one uses the 6-clip. I use them in a classic RAPID 1 in the SOHO (Small Office / Home Office) and had as yet no failures.
The book image of the 8 clip, their position in the vending machine and its enforcement and penetration I am fully satisfied and recommend this explicitly, in its metallic simplicity almost elegant looking, product.
To write a review about staples, can be regarded as a challenge.
