This is a set of 5 long screw on crimpy edges.

They're great on the lips of volumes to make a positive pinch,  just over the lip of an overhang, or use them just as they are.

They're long enough to match on and are first pad deep, apart from the top one, which is second pad deep. You can pair them up too to make wide pinches 

They are made of Dannomond and screw on to the wall with screws (not included)
