Black/white/clear Fountain Pen Tube?

[FilthyFrank]

Sorry if this is in the wrong section, I'm on my phone & having a hard time getting around. I've noticed that all the pen tubes, as in the metal part within the pen that you don't really see, are all made of brass or copper. Are there any black, white, or clear ones?

Inexpensive ballpoints often have clear or frosted plastic tubes that hold the ink.

Well, Copper is probably a less common material, Brass, Steel, Aluminium are very common, but so are all kind of Thermoplastic and Thermoset Plasticsas well as Resin of all kinds ( non petrol-chemical type ). Color of the set material varies. Material like Melamine come naturally in white but are seldom used for pens. Clear PPTE is rather common and used in many Clear barrel pens. In any case for most Plastic, the color is just a matter of what goes in when doing the mix. And for metal its about whether you got it painted ( or any process of finishing )

brass and aluminum for parker like carts for G2 like carts you pretty much halve plastic to deal with

Inoxcrom does have clear plastic Parker like carts as well as chinese knock-offs which comes in a white opaque plastic

pilot also comes in aluminum and plastic proprietary refills (S20 BP over Metropolitan BP) for example

BRFN-30EF, BRFN-10F pilot refills for example
