Hello, thank you very much for your kind question � � Our bag is made of faux leather material and is designed for everyday use. However, the product structure is not completely sealed, there is a risk of water ingress due to the magnetic cover design. For this reason, we do not recommend using it while swimming. Exposure to water and intense humidity can not only shorten the product life, but also damage the items inside. If you still want to add an elegant touch to your beach style, it is ready to accompany you with its elegance � � We are always happy to answer any questions you have. With love,
