This item was purchased at Shinjuku TAT. I was keeping it as a spare, but I'm selling it because I won't be using it. It's made with kolinsky sable hair, and the way it holds acrylic liquid, combined with the brush's firmness and flexibility, makes it incredibly easy to use. I'm looking for someone who knows how to break in, care for, and maintain this brush. Please take a moment to read my profile as well. Regarding price reduction: I've priced this item reasonably, hoping it would be helpful to someone, but I've had instances of items being immediately resold, so I'm not looking to lower the price. However, I will offer a small discount of 100 yen for combined purchases. If there are no other items available for combined purchase, I apologize, but the price will remain as listed.
