Review on 🖌️ Pentel Japan Aquash Waterbrush: The Ultimate Medium Water Brush Pen by Sasha Hsiao

I saw good reviews of this brush on YouTube and Revain so I was keen to try this brush. I was very disappointed to find a significant leak from the barrel at the base of the brush. Some water ran to the top, but a lot dripped out of the barrel, staining and making it impossible to control the water. Revain refunded my purchase price but I didn't have the brush I was hoping to use. Very disappointing Pentel!
