Rowney Premium Watercolor Brush "DIANA" Kolinsky Sable Brush Round No. 4 [Unused] - Rare Size The highest quality natural brush made by the British company Rowney "Diana" Diana, made during the peak of Kolinsky sable brush production, is now discontinued, and unused brushes in particular are a phantom item that can never be obtained again. This round brush uses luxurious tail hair from the finest Siberian black sable, making it ideal for advanced techniques such as watercolor and tempera. It has a sure tip alignment, rich paint absorption, and exquisite elasticity, making it a paintbrush with ideal expressive power. Completely unused With tip cap Comes in a dedicated vinyl case Tip x Width: 19.0 x 3.0 mm Tax-included price: ¥4,950 [How to Prepare the Brush for First Use] * Because it is unused, the brush hairs have been treated with "sizing". Be sure to do this before use. ① Gently loosen the brush hairs with your fingers from the tip. ② Apply water to the brush head and carefully wash away the sizing glue. ③ Shape the brush and hang it upside down in the shade to dry. * The brush hairs and handle are in good condition because they are unused, but due to their age, the vinyl case has fine scratches, so please purchase only if you can accept this.
