The LeGrand twist pencil in 0.9 mm calibre does have a lead reservoir but must be reloaded from the front: remove the old lead, turn the upper part to the left until a slight click is heard, insert a new lead and feed it into the pencil by turning left. If the mechanism continues to click without the lead advancing, remnants of the old lead are presumably stuck in the tip; turning right makes the lead end visible so it can be pulled out with tweezers. The LeGrand twist pencils are regarded among collectors as the best on the market and not prone to fiddling in meetings. With persistent defects forum members recommend first going to a competent Montblanc specialist dealer (e.g. Knoblauch in Heidelberg or Bürohaus Lehr in Trier) for an on-site check, before sending the pen in to the boutiques in Frankfurt, Stuttgart or Hamburg.
