The threat of viruses has been felt worldwide. In such an environment, individuals are taking protective measures such as handwashing, disinfection, and wearing masks, leading to a demand for related products. In response, we propose sandals equipped with antibacterial and antiviral properties. This product has copper powder directly baked into the sandals. The sterilizing effect of copper has been known since ancient times; for example, in China around 1600 BC, copper coins were used for treating illnesses, and studies of old copper handrails installed over 100 years ago have shown that they still retain antibacterial effects. These sandals possess the beneficial effects of copper. Additionally, the feet are often where viruses are detected. Shoes that are worn while walking around may contribute to the spread of infections. You may be transferring viruses and bacteria from contaminated ground or floors to the soles of your shoes, making antibacterial properties on the soles necessary. 【Features】 ■ Antibacterial ■ Antiviral ■ Made in Japan *For more details, please refer to the PDF document or feel free to contact us.
