The Handle

The color of the handle is black, which gives it a luxurious feel. The color is the same as the following:
 

The letter, "Koyudo" written in Kanji is printed on it.

As the width of the handle is gradually widened to the bristle, it's easy to take holds.
 

The Hairs

 

What a special feature of this item is "a full head of the luxury soft goat hair"! 
The densely packed bristles will pick up the perfect amount of powder and allow you to easily spread out an even thin layer by stroking brushes with powder in a circular motion. 
Then you can use this like powder puffs. It uses Sokoho, a high-quality hair among goat hair.
(Sokoho - hair at the bottom of goat's throat It has moderate elasticity and durability. Picks up the proper amount of powder.) 
It's very soft and makes me feel that I use a powder puffs not a brush.

I have felt that this brush has more durability than ones from other makers.
The tip of a brush normally become spread out while using it.
However as for this brush, the tip hasn't been spread out after a few months of use because it is highly densed.
