This item was purchased at Shinjuku TAT. I've been storing 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, clean, and maintain this brush. Please take a moment to read my profile as well. Regarding price: I've priced it reasonably, hoping it would be helpful, 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'm afraid I'll have to sell it at the listed price.
