Just that really.
I had to deliver some single sheet flyers around our area for a local campaign. The choice seemed to be to end up with a load of flyers crumpled up like concertinas or having my knuckles scraped raw by the bloody bristles as I tried to protect the flyers by laying my hand on top to keep the bristles out of the way.
Bastard things.
(If it's draughts the owners are worried about do what we did and install a wooden flap on the inside).
