While the locket is designed to securely seal, it is generally recommended to avoid prolonged exposure to water (like swimming or showering) to protect the contents and the integrity of the seal over time.

The locket and chain are typically made of stainless steel or other jewelry-grade metal, known for being durable, hypoallergenic, and tarnish-resistant.

A filling kit is included with your purchase. This kit usually contains a small funnel and a tiny scoop or poker tool to help you carefully transfer a small amount of material into the locket's chamber.

The locket likely has a secure, screw-on bail (the loop that connects the pendant to the chain) or a small, discreet screw on the side or back. Once the contents are in place, the screw is tightened to seal the chamber.

While the screw provides a secure seal, for permanent closure and peace of mind, many people choose to apply a tiny drop of superglue to the threads of the screw before tightening it fully. This makes the locket non-reopenable.

This is a keepsake locket, designed to hold only a very small, symbolic amount—typically a pinch of ashes.
