This leaves the 0.7 mm which works even partially to my liking. It takes a bit of practice to develop the one handed dexterity to advance the lead. The two handed method is more sure, but cumbersome. These are generally well made. The problem is the extremely high price for replacement inserts.
Several companies make refills for the smaller pen which drives down prices.
The larger pen only has extravagantly expensive refills only made by Montblanc and warehoused by suppliers so long that they are almost dried out by the time you buy one.
