Unfortunately, the staples do not fit into standard staplers. On the one hand, the web width is a touch too narrow (= they don't slip on the staple rail), and on the other hand, the individual staples are too wide (= staples clogged).
The clip size is unusual and does not fit !! in standard European tackers (I have now tried the 6th without success)! Apparently only the Takkurat can handle them. If you don't have that, you'd better use local brackets.
