This bracelet is made with a stainless steel padlock shaped urn that has been engraved with a single letter in the center. Urn has been added to a stainless steel paperclip style bracelet. Lock urn is just under 3/4 inches from top to bottom, including the loop at the top. Urn allows a small amount of ashes to be put inside using the screw on the bottom side. After filling the urn, I'd suggest adding a small amount of glue to the end of the screw before tightening. I don't recommend using the item until the urn has been filled and securely fastened with glue. This listing comes with an urn fill kit. ***Please Note: this urn is not entirely hollow, but does allow a small amount of ashes to be put inside. If you are wanting an entirely hollow urn, please see my cylinder urns or sterling silver heart urns. Use the pull down menu to select your crystal month, bracelet size, and font preferences. Last picture shows the font options for the single engraved letter. Only the center letter (larger in the middle) of each font shown would be used for this item. (Bracelet size is not the same as wrist size) If you need more quantity that available for purchase, please contact me before checkout for more information. Comes wrapped and ready to gift if needed. Since this is a custom made item with your specific engraving after checkout, it is not eligible for return or exchange.
