If it takes international cartridges then yes. Check the pens website for verification.

It'll fit any fountain pen that accepts the international cartridge, which should be "most pens" for what it's worth. I myself have never seen the pen you're talking about, sorry about that.

It fits my Waterman Laureat. It is very short and my pen will not accommodate storing a spare. It is not the longer version cartridge that came with my pen.

It fits my British Berkefeld. Just measure your opening, and compare it to the specs.

Be very careful. The one you asked about (367923U) does NOT come with a pen and will not work with a pen if you buy one separately. To get the pen make sure the model number is 367927U.

I am pretty sure it will, yes. However, I am not a pen expert. Sorry for the waffle.

Internal size generally fits every fp unless specified otherwise. I have a Faber-Castell Basic Metal Fountain Pen and they recommended a Graf Von Faber-Castell Fountain Pen Converter (http://www.amazon.com/gp/product/B00439V75Q). Not sure if that means international size will not work but at least it's some info.

I am almost certain it will NOT. this fits very specific models. kydex is molded specifically to the correct dimensions

Can't answer that. You might check your specific pen on the website at http://www.spacepen.com/cartridge.aspx

Sorry, don't know if it'll fit that model. I know it fits the QC-2 and QC-15.

They are supposed to be "universal," and they fit both of my fountain pens. They are 1.5" long and 0.25" in diameter at the base.

I really don't know. You need to look at the shape of the cartridge, especially the end of the cartridge with the plastic piece on it that goes inside the pen. The shape of the cartridge and the end piece need to match your old cartridge.

Check the length of your current refill. If it is 4 1/4" it will probably fit as the Schmidt Long is pretty generic to a lot of pens using a refill this long.

That pen looks exactly like mine and they work in mine. I thought mine was called the Parker Jotter but it should work, they look identical. I wouldn't hesitate to buy it for that pen.

I have a "double heart" Paper Mate pen, rather slim, with chrome upper part and black lower part with a chrome tip on the lower part and the refill fits exactly (it's exactly the same type of refill that came out of the pen when I changed the refill originally). So I think you're good to go.

I have the DeLonghi EC155 and now have a collection of various sized tampers bought trying to find the right one.... The 51mm Vktech fits perfectly. I'm guessing many DeLonghi's use the same size filters as mine, but cannot verify.... (Note: even if it's the wrong size, it would make a great paperweight....)
