I like those early black eyedrop fillers, I'm not sure what they are made of. There are intersting materials in new low priced pens too, but I don't know how cow-horn behaves over time. I think it's one of the better materials, since spectacle frames can be made of the. I think some amber, horn and tortoise imitations are cellulose acetate, it can have a translucent quality.
    At the beginning of the thread, there is a list of materials. Horn, and early plastics, casein, or galallith as is more commonly called, is mentioned.

    Regarding black eyedroppers, you can find them (but seldom) in bakelite, it is a fragile material to work with, hence the production not lasting long. Moreover, easily breakable. Many of the black eyedroppers, as you say, are mostly hard rubber made.

    I should make a list of them and note down their various caracteristics just to get a better view of the situation. I have noticed some early celluloid / acetate are still intact and in good condition after 80 years, I assume there were quality differences in the 20s and 30s too. Some of the new materials mentioned are intersting like Juma and Elforyn, expecially if they are nice and durable. The Ultra Resin some claim to have should be received well (resin is such a wide term). I recently read of elephant slaughtering (again!) and I hope materials like Elforyn will be accepted as a worthy substitute for ivory. The real thing will always be the point of referance, the odd thing is that celluloid/acetate and hard rubber have become standard points of referance for nice and durable materials. Some times I wonder where we actually managed to improve on things.

    Still — apologies to your wallet. Looking forward to seeing the collections this thread yields.

    (My next significant pen will be delrin, I think.)

    By strange coincidence, my delrin pen arrived today. In red, from Worcester Pen Company, with gecko rollstop. It has a lovely soft warm feel to it.

    Here's my recent hand made or small manufacturer purchases :

    Wow! I think you have a very cool basis for this collection of modern fountain pens, and I would love to try the tactile feel of writing with each. I once held Delrin with my long-lost 2000, but c'mon..., concrete?! I gotta check Contour Concrete out!

    The concrete is hard, but has a very smooth finish. I think the agregate used in it was powdered, not the lumps you see in bridges. It's also surprisingly warm to the hand. The only comment is that it is also slightly absorbent, so seems to be discolouring with oils from the skin. All part of acquiring patina, you know. I will try not to drop it to see if it breaks.

    Also note the O-ring to seal the cap. I've not seen that before.

    Yes, that's where I first saw it, after Catbert's post #36 in this thread.
    I found a dealer in Europe selling the pens for less, and without the messy customs processes and costs.

    Nicely done! The texture on the Matthieu Faivet pen is interesting — rather like bark. Great roll stop.

    I was tempted by some similarly fine-grained concrete desk accessories. I like the look of the 22 Studio pen but 45g is a bit heavy for me.

    Re the cap o-ring, the Caran d'Ache Léman does something similar.

    That's what M Faivet calls Tres texture. Nice feel to it, I wonder if it will smooth out over the next 40 years, like my Lamy 2000 has over the last 40. I can't wait to find out.....

    Just to re-activate this thread, here are pictures of my Elforyn Super Tusk (ivory substitute) pen made by Teodor Mircea.

    Nice fat pen, lovely workmanship, the material is smooth and has the striations of real ivory.

    I used to have hair that long!

    I used to be that thin!

    I used to wear shorts that short!

    Nostalgia isn't what it used to be.

    Here is another ivory substitute, a modern celluloid once sold by Mark Hoover and David Nishimura. I had Brian Gray make this lovely pen, with two sections in black hard rubber and ivory celluloid.

    That looks very smart. Is the surface textured, or is that colouration in the material? Difficult to tell from the photo.

    The surface was smooth and the color variation was within the celluloid. Alas, I never seemed to embrace white pens, and I sold it in the condition as you see.

    The American Art Plastics URL no longer works, but you might want to contact Mark Hoover directly (where the blanks were warehoused) to see if he has any available: http://www.lbepen.com

    Back from my USA trip, which included the amazing San Francisco Pen Show.

    Look what fell into my pocket while I was there. A new metal for the collection.

    Ultem — 'a polyetherimide designed for use in high-temperature environments', according to this review.

    Both material and maker are new to me.

    I was a bit too late enquiring about that very pen when the blogger announced that he was selling to reduce his collection.

    Unfortunately the makers only sell via Instagram, which I won't use. Call me old fashioned.
