Note for Note of another buyer, the pins to swap the old rolls with the pins of the new roles:
I tried to pull the pins in my old rolls out (after all, I wanted to throw away these roles yes). That was not in my roles by force. Obviously, there are roles where this method fails.
But no matter - I am completely at peace.
The new roles are silent, a braking effect is there, but does not interfere when it is seated and my floor is spared.
These roles and these retailers can I highly recommend.
