What is your opinion of the quality of this item? Most International Converters for nice pens are all made by the same company in Germany "Schmidt" they make MontBlanc Converters as well as Graf Von Faber castell and Visconti and others. so they quality is consistent. they make very nice converters Overall this Converter is well worth the money and it worked perfectly inside my mont blanc star walker to convert it from cartridge only. I purchased this Graf von faber castell converter because the mont blanc converter is too long to fit inside the Mont blanc star walker. this faber castell converter is a very nice fit on my star walker fountain pen and works just as a mont blanc converter would.
