Thank you for viewing. This is a set of two "Midori Mayu Mayu Balls" from itoguchi, known for their gentle touch and ability to softly remove dead skin cells during face washing. I encountered itoguchi during a stay at a hotel in Nagano Prefecture. They develop skincare and haircare products using Midori Mayu (green cocoons). Compared to the typical white cocoon, these cocoons retain the characteristics of wild silk, containing a higher amount of silk components and nurturing the skin. I've been using these repeatedly. - Brand: itoguchi - Product Name: Midori Mayu Mayu Balls - How to Use: Use after warming in 40°C water - Color: Yellow - Quantity: Set of 2 Please refer to the HP for product details.
