The CalExotics Anime Stroker Misty is a compact male masturbation sleeve made from thermoplastic elastomer (TPE). It is designed with a textured internal chamber and a closed-end structure intended to create suction during use. 

Key features include:

• Material: Soft, flexible TPE.
• Internal Texture: Ribbed and nubbed interior walls.
• Maintenance: This item is typically cleaned using warm water and a mild soap or a specialized toy cleaner.
• Compatibility: Because it is made of TPE, it is recommended to use only water-based lubricants, as oil-based or silicone-based lubricants can degrade the material over time.
