white opaque pens and alternatives

Uni Mitsubishi (Signo gel pens) and Pilot did choose not to disclose information about their products and companies (information on Uni : 2017; newest information on Pilot: 2021)

Faber-Castell is a distributor for Uni Ball and informed me (April 2021) that all the Uni Ball products they distribute, are free of animal derivatives; however, this concerns only the materials not Uni’s status (concerning the cruelty-free topic);

Speaking of Faber-Castell, these might work for you:

  • Pitt artist pen in white (my opinion when I got them when they came out: not very opaque; buildable, for small highlights , best stored horizontally)
  • watercolour pencils e.g. Albrecht Dürer; wet or dry application; of course pencils will last you practically a lifetime
  • gelatos – watercolour in stick form; blendable with finger;
  • oil pastel in white – should be very opaque
  • soft pastel
  • white pastel stick or Pitt pastel pencil; lovely over watercolour and alcohol markers …

Those are just examples (information from 2021); of course you can use any  gouache or acylic paint (or pens, pastels, …) free of animal ingredients; my other brand informations on e.g. Culture Hustle (Stuart Semple), Liquitex , Golden Paints, Qor Watercolors and others are older (2017, 2018) , but you might want to look into them.

It depends also on what surface and other medium you are working with. I for example used gelatos in the past on canvas and like Pitt pastel pencils over watercolour and alcohol marker.
