💡 How to Care for Your Internally Threaded Curved Barbell
- 💡 Clean weekly with mild soap and warm water, gently scrubbing the ball ends and shaft to remove buildup and maintain the polished shine
- 💡 Dry thoroughly after swimming, showering, or workouts to prevent water spots and maintain the surgical steel’s mirror finish
- 💡 Store separately in a clean, dry place to prevent scratching the polished surface — internally threaded jewelry should be handled carefully to protect the internal threads
❓ Frequently Asked Questions
Q1: Is this internally threaded curved barbell safe for a new or healing piercing?
For healed piercings only. This curved barbell is made from 316L surgical steel, which contains trace amounts of nickel. For fresh or healing piercings, we recommend implant-grade titanium due to its nickel-free composition and superior biocompatibility. However, internally threaded jewelry is gentler on piercing channels than externally threaded options, making it a good choice once your piercing is healed.
Q2: What’s the difference between internally threaded and externally threaded?
Internally threaded jewelry has the threads inside the ball end — the smooth post slides through your piercing first, then the ball screws on. This is more comfortable and causes less irritation. Externally threaded jewelry has the threads on the post itself, which can catch and irritate your piercing channel during insertion. Internally threaded is the premium standard for quality body jewelry.
Q3: Can I wear this surgical steel curved barbell while swimming or working out?
Yes, 316L surgical steel is waterproof and sweat-resistant. You can wear this internally threaded curved barbell during workouts and swimming. However, rinse with fresh water after exposure to chlorinated pools or saltwater, and dry thoroughly to maintain the polished mirror finish.
Q4: How do I choose the right size?
Measure your current jewelry for gauge (thickness) and length. For eyebrow piercings, 16G 6-8mm is standard. For navel piercings, 14G 10-12mm is common. Ball size is personal preference — smaller balls (3-4mm) are more subtle, larger balls (5mm+) make more of a statement. If you’re unsure, consult with your piercer before ordering.
