For calligraphers and sumi-e artists who appreciate deep, rich ink, this Kuretake Sumi ink stick is a classic.

The 'Tenjo Taikaze' Type 5.0 produces an intense, pure black that's perfect for bold, dark work.

But here's the cool part – when you grind it to a lighter consistency, it reveals beautiful brown tones with a hint of purple, giving your artwork incredible depth and variation.

It comes in a solid stick form (about 2.8 x 0.8 x 3.9 inches), so you grind it with water on an inkstone to make fresh ink exactly how you like it.

This traditional method gives you more control over the ink's texture and tone than bottled inks.

A must-have for serious Japanese brushwork, sketching, or anyone wanting to explore the meditative art of preparing their own ink.
