How to Measure Your Jewelry









Material & Fit Guide
Twolobes jewelry is crafted from 316L stainless steel, titanium, and borosilicate glass — hypoallergenic, durable, and body-safe.
- Stainless Steel: everyday durability and shine.
- Titanium: lightweight, nickel-free, ideal for sensitive skin.
- Glass: smooth and non-porous for healed piercings.
All materials are safe for long-term wear when used in fully healed piercings.
Safe Stretching Tips
- Always stretch clean, healed lobes.
- Increase only one size (about 1 mm or one gauge) at a time.
- Use a small amount of oil or balm to ease insertion.
- Wait at least 6–8 weeks between stretches.
- Listen to your body — if you feel pain, stop and downsize.
🖤 Healthy lobes = happy stretching.
