In on-site retail Lamy pen holder can be found very rarely with the line width F. Because I was looking for a new and stable Lamy fountain pen, I ordered this copy. The delivery arrived quickly at the packing station. The penholder meets my expectations. It is well made, has the classically simple design of Lamy and I like to use it at every opportunity. Meanwhile, my wife and our daughter are supplied with such a pen holder and both are also satisfied users (though they have a black or red pen holder). That's why I like to speak from a strong buy recommendation.
