This is an absolutely stunning piece that is purposely designed to be a sophisticated and classy keyring or handbag charm. This floating locket has a glass front and back, the metal is stainless steel so is therefore hypoallergenic. This is silver coloured stainless steel, not real silver or real silver plated. The locket is openable therefore great care must be taken. It secures itself closed with strong magnets and you can open by opening it like a book. The opening nature means that they are perfect for adding in your own tiny items such as a lock of hair. Locket measures approx 30x7mm. Clip attachment with double loop fixing is 44mm. Measurements can be seen in photograph 3. I can supply these with necklace chains instead of keychain attachments for this same price. I can also supply with floating charms for a small price for these. Please message me prior to ordering as i have many styles of chain and lengths so we can finalise prior to purchase.
