How it grips. The clip is an outer frame and an inner tongue joined at the flower end, 1.2 mm thick. Paper slides between the tongue and the frame, which splay apart the way a wire clip's loops do and spring back — the same geometry as every made paper clip, kept generous so it lasts. The 22 mm flower is a second layer fused on top, the centre a third color. The whole pack is made flat on one plate.
