Material:

The sleeve inside the cup is often made of body-safe materials, such as medical-grade silicone or thermoplastic elastomer (TPE), which are soft and flexible to provide a realistic feel.
Some products also feature a 'pussy' or vaginal-shaped opening, which is designed to replicate the look and feel of intimate anatomy.

Discreet and Portable Design:

The cup is often designed to be discreet, with a sleek, portable shape that's easy to store and carry. It’s meant to look like an ordinary everyday object, which makes it easier to hide or take with you.

Easy to Clean:

Most masturbator cups are easy to clean, often with removable sleeves that can be washed separately. It’s important to clean these toys thoroughly after use to maintain hygiene and the longevity of the product.
