Questions about GBC Click-Bind

For me it was 50 pieces. 12 breite☺️

No. Only with the clickman. But I think it's much better (it's worth buying the clickman device)!

It is usually due to the number of sheets that have space in the spine. This will be the case? Just make sure that the spine width is approximately the same as the number of sheets. Otherwise it doesn't look great if the binder is very narrow and the spine is much too wide. I hope it helps. Otherwise it's a great thing to do.
