💡 How to Care for Your Titanium Internally Threaded 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 — titanium is naturally water-resistant but drying maintains the 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 titanium internally threaded curved barbell safe for a new or healing piercing?
Yes! ASTM F-136 implant-grade titanium is the gold standard for fresh and healing piercings. This internally threaded barbell is 100% nickel-free and biocompatible, making it safe even for sensitive skin during the healing process. The internal threading adds extra comfort during insertion and removal — it’s the best choice for healing piercings.
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 titanium internally threaded barbell while swimming or working out?
Absolutely. Titanium is completely waterproof and sweat-resistant. You can wear this internally threaded curved barbell in pools, oceans, and during intense workouts without worrying about damage, corrosion, or discoloration. Unlike plated jewelry, solid titanium won’t chip or fade.
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.
