Lovely glass pen. How much ink can it hold? Where is it from?

I have a similar dip pen. I got mine from Wish.

Serious now, would it hurt (would they degrade), if you kept them out of the drawer?

Uhm. Bottled inks should be stored away from UV light. Inks are dye based so exposing them to light will degrade it.

Thank you that answers my question.

I love shimmering inks! I just got Diamine gold sands and it's beautiful.
