Holds well in my 0.25" hole I drill for the dip pens I make. Holds the nibs as expected.

Bought these for future use in my dip pen production. They have a nice gauge stainless steel material and will buy again.

Best price for the best quality ferrules!

High quality, well packed, and quickly shipped.

This simple and utilitarian SS ferrule has been saving me and my grassroots calligraphy classes (at public school with no funding) a lot of money. As a passionate calligraphy teacher, Osprey Pens has been beyond kind sending us little good bags every few months with inks and spare tools. Using straight holders that we machined in woodshop, I have been able to create a class set of dip holders to try and teach calligraphy at our own cash strapped private shool. Normaly, I would have to keep re-ordering ferrules as they were always made of spring steel until Osprey came out with this SS rust proof ferrule. THank you to the entire team at Osprey Pens, our school calligraphy program would not be possible without their genoristy and innovative solutions.
