Theoretically well, pliers makes high-quality impression. I have not yet managed, the Snaps to move reliably to close. More pressure, less pressure, thinner fabric, several layers, thicker material, repeatedly zukneifen etc pp ... - mostly remain the Snaps functionless and the substance has a hole (logic). Perhaps I find the trick sometime or out there will try it with original KamSnaps. First, however, the desire has passed me.
