Bright ink colors may not be my primary wheelhouse, but despite being pleasantly surprised by the character in the 18ml TWSBI inks when I first swatched them I've rarely reached for them since and these inks deserve better! The frosted glass bottles are good too. I used 8 TWSBI inks to paint in the Dominant Industry Ink Archiving book yesterday.
