Technology based on terahertz waves. This health product activates ingredients and enhances overall vitality. Retail Price: ¥129,600 (Expiration Date: 2026.12.06) This was a gift. It's an expensive and valuable product. (Only one left) I can't use it all, so I'm offering it at a reduced price to someone who will. Regarding the condition, it's based on a visual inspection by an amateur, so there may be oversights. Please refrain from purchasing if you are not understanding of home storage, are sensitive to smells, or are overly concerned about used items. Thank you for viewing.
