This is a Tsujichu Shoten tsuge comb, a gift. It's about 11.5cm long and has "coarse teeth." Includes shipping, box, and case. Discounts are available only for combined purchases. I tried it once on clean hair, but I have another one I prefer, so I'm reluctantly selling this one. Please refrain from purchasing if you are concerned as it is not brand new. I am hesitant to sell it, so please understand that I may delete the listing suddenly.
