Arrived as described. Piston filler works , but does not fill inkwell fully. 

Even using an unused No. 24 unit, I couldn't achieve full suction.
When I checked with Montblanc, they said that they recommend not filling the pen completely because it will leak ink if you do.
If you encounter any problems using it, please contact us at any time.
