100% Latex Dental Dams are designed as a barrier for use while performing oral/vaginal or oral/anal sex. When properly used, Satin Dams may help reduce the risk of transmission of many STIs, including syphilis, gonorrhoea, chlamydia, genital herpes, and HIV. However, they cannot eliminate risk. During intimate contact, lesions and various body fluids can transmit STIs. Therefore, a Satin Dam should be applied each and every time prior to sexual contact. Before using, please read the enclosed directions for use.
