The skin in the delicate zone of women is thinner and more delicate than the lips, and the transdermal absorption rate is 42 times that of the upper arm. Because it is a more sensitive and important place than any other part of the body, safe and secure sanitary napkins are used. <About the bioRe Project> The cotton used is fair trade organic cotton born from the bioRe Project, which conducts social projects such as the employment of local women. It has a natural softness that synthetic fibers do not have. ★ About promotional leaflets When ordering, please contact us in the chat "Leaflet request"!
