💡Why Titanium?

Most “hypoallergenic” earrings aren’t actually safe for long-term wear.

Titanium is:

- Nickel-free and biocompatible
, so it won’t irritate even the most sensitive skin

- Used in medical implants like hip and knee replacements — that’s how safe it is

- Lighter than stainless steel but twice as strong — no droopy lobes here
