Stands for Ultra Realistic 3.0, a trademarked sex toy material with a soft, lifelike feel. UR3 is a type of thermoplastic elastomer (TPE) that does not contain any phthalates. It is hypoallergenic and considered suitable for people with skin sensitivities.

UR3 can be cleaned with sex toy cleaners or with warm water and a very mild soap. Because it is porous, it is very important to clean it after every use. UR3 toys often ship with a “renewal” powder, which is commercially available; this powder helps the toy to retain its soft, hyper-realistic feel. Users should store UR3 toys in plastic bags or in dedicated storage cases to reduce the chances of microbial growth.

UR3 is commonly used for male sex toys. It is compatible with water-based lubricants, but silicone- and oil-based lubricants can permanently damage the material.
