These are chopstick holders, but work great for resting your paintbrushes on. Aren't they cute? I found them at a Japanese shop. Maybe it was Tokyo Lifestyle. I don't remember.
Now that I look back at the picture, I want them all! I just bought the little doggie in the second photo. I wanted to draw in ink with that stick, but tsch, it has been sitting on my easel for 2 years! It's just decoration at this point.
