PTERO - Large
FAQ
-
Choosing the right size is essential for both comfort and security. Measure your flaccid penis length and the circumference at the base of your scrotum, then compare with the product size chart.
• First-time wearers should start with a slightly larger ring size to allow for adjustment.
• If you experience pinching, numbness, or discoloration, remove immediately and try a larger size.
-
The BEISAR PTERO - Large is made from body-safe, medical-grade materials that are non-toxic, odorless, and skin-friendly.
• Always inspect the device before use for any cracks, sharp edges, or damage.
• If you have known metal allergies, check the material specifications before purchasing.
-
For easiest application, put on the PTERO - Large when fully flaccid.
• Apply a small amount of water-based lubricant to reduce friction during fitting.
• Thread the base ring behind the scrotum and penis first, then fit the cage over the penis and secure the lock.
• To remove, unlock with the key, gently slide the cage off, then remove the base ring.
• Never force the device on or off. If you experience difficulty removing it, apply lubricant and remain calm.
-
Extended wear requires gradual adaptation. We recommend starting with a few hours and slowly increasing duration as your body adjusts.
• Check skin condition regularly — look for redness, chafing, or swelling.
• Remove the PTERO - Large immediately if you experience pain, numbness, tingling, or skin discoloration.
• Always remove for hygiene cleaning at least once daily during extended wear.
-
When used responsibly, the PTERO - Large is safe for adult use. Follow these safety guidelines:
• Always keep a spare key accessible in case of emergency.
• Never wear during sleep until you are fully experienced and comfortable with the fit.
• Discontinue use and seek medical attention if you notice persistent pain, swelling, or loss of sensation.
• This product is intended for consensual adult use only.
-
Clean your PTERO - Large before first use and after every use.
• Rinse thoroughly with warm water and mild soap or a dedicated sex toy cleaner.
• For metal devices, dry completely to prevent oxidation. For plastic or resin devices, air dry before storing.
• Do not use alcohol, bleach, or abrasive cleaners.
• Store in a clean, dry pouch away from direct sunlight.
