Condoms made from natural rubber latex, according to international standards and without aesthetic defects. Features Diameter: 52mm Length: 160mm Shelf life of at least 36 months Material: natural latex, smooth shape Type: Single-sided, smooth surface Style: Tank top Surface treatment: Lubricated with silicone oil Lubrication amount: equal to or less than 400 mg Instructions for use We carefully remove the wrapped condom to avoid tearing it while opening the package. We find out which part is unfolding by gently unfolding it. While we put it on, we hold the tip at the end to make sure there is no air left inside. We always use water-based lubricant (water-soluble). We never use anything oil-based or petroleum-based (lipid-soluble) such as jelly, oil, creams, baby oil, petroleum jelly, lotion, or other lubricants. Oil-based lubricants will damage the condom and cause it to break. Precautions We check the expiration date and the CE seal on the package. We do not store condoms near heat sources (for example, above the TV, near radiators) or in places exposed to direct sunlight, as heat destroys them. This product contains natural latex which may cause allergic reactions. The condoms are nitrosamine-free. They do not contain traces of NDMA 90, but this is in accordance with the specifications defined in directive 93/11/EEC.
