Osprey #6 EEF nib are some of the best fountain pen nibs you can get if you value fine points like I do.

Son fantásticos.

Bought the EEF fine version. Hair thin (like. Japanese EF) and excellent flow. I use it for drawing. I’ve bought several pens and nibs from this company in the past and will continue to do so. Thumbs up. The only gripe is it took forever to get through Irish Customs - but that’s not Osprey’s fault.

I've purchased my fair share of BB nibs and while other companies can produce BB in Gold, the steel BBs have always been a disappointment.

I've received a few(five, from two different orders) nibs from Osprey and they have all out preformed every single steel BB from other manufactures. Flow has been significantly better and the line width on the page is actually what I would call a real BB.

I always think that line width is king, but comparing Osprey nibs to the other steel BBs I realize flow makes a significant difference to how good I feel about the nib. A wider line that does not have enough flow can make a lovely black look grey and cheap.

My last and probably most important point in this is QC, I don't know if the manufacturing process is just better or if they get tuned but I have yet to see the tipping/slitting issues from "luxury" manufacturers. I've dropped $300+ on a nib that required rework and tuning multiple times. That hasn't been a problem I've run into with these BB from Osprey.

I've been using these nibs for the last four months and they are awesome. They write very smoothly for me and I find them to have just enough flex to them without feeling springy. I particularly love the EF. Now whenever I get a new pen, I pick up one of these to put in it.

I'd like to add that Osprey's customer service and communication are outstanding. Every time I've had a question, someone gets back to me. They are a pleasure to deal with.
