Thank you for your question! At SSIS, we offer water-based, silicone-based and hybrid lube. All of these are safe to use with all of our condoms! Most condoms already come with silicone-based lube, and we offer one type of unlubricated condom as well. Even for lubricated condoms, adding additional lube makes them even more effective at preventing pregnancy! Using any kind of lube that contains oil can degrade condoms and cause them to break, but all the lubes we sell at SSIS are safe to use with condoms!
