Materials: 999-Fine Silver & solder \r\nMeasurement : about 2.8MM (Width) x 2.5MM (Depth) \r\nThe Size of letter stamps : 1mm The options of letter stamps : capital-english-letters, &, 0 to 9. The quantity limit of characters : about 8 at most. (A surcharge will be made, if over 8 characters) I’m happy to customize. Each letter has been individually hand stamped. Because of this the lettering may have slight variations in the spacing, depth of the impression and the alignment. This is the nature of hand stamped jewelry and part of its charm. All handmade jewelry has slight variation from piece to piece, so it is always different from one to the other. \r\nA logo of summermoon, symbolizing positive vibes, and the number 999 (indicating fine silver) will be hand-stamped inside.
