Old but I still love it. I adore Tjordie and Ace(actually all of Silence's creations) 'cause of their fun designs and personalities.
Anyways this is a soft slat of wood that holds paints, watercolors, markers, and pencils quite well. I use a sealer when i'm done to preserve to colors as well as bring out the woodburning details I put in.
I wont do more than two characters per slat unless its just headshots. Up to 3 maybe 4 headshots will fit without loosing detail workspace.
These are $10 for a 2 char. bust with lots of attention to detailing.
For a simpler one maybe around $6.
**Prices are always nagotiable. Mostly depends on how much specific detailing you'd like.

Both Ace and Tjordie belong to Silence here on FA or Kohta-inowa on DA
