It was announced a capacity of 30 sheets. I would rather say 20, because it depends primarily on the depth of the staple 24/6: 5 mm - not curved (...). They are large enough for the first and last leaves of a notary bundle do not tear over time, or as rotation on small staplers "baby".
The stapling action is particularly cleanly on this model.
It does not say that Leitz and offers: the small plateau where crashes the clip comprises two series of small holes face to face and oddly good spring underneath. Pull it up and flip front / rear for large thicknesses.

Look still the model above, 5549, guaranteed for 10 years. The congestion is substantially the same: 0.5 cm higher L., thinner l, 80 g more.. A fixed power system simpler and probably more durable. Accepts 250 24/6 and 24/8 to 40 sheets, and deadly super strong Rapid 26/8 +. Mouth depth 6.4 mm. Pretty anodized metal exceeding mm. 2 more but free port, so cheaper!
If I really need in my school bag for series of 35 sets of 6, it is she that I carry. 400g ...
