A blended oil made from carefully selected citrus and mint blended with a completely original recipe. The blended oil, which was sold as a safety screwdriver set, has been sold separately in response to customer feedback. Although it is a blend similar to the scent of the mask spray, we adjust the ratio of the blend according to the condition of the oil and strive to create a scent that is easy to use. ・ It is a blended oil with a refreshing scent that can be used by a wide range of people, such as beginners, those who are worried about drowsiness due to studying or driving, and those who cannot concentrate on work due to working from home.
