"We very much appreciate the quality of the memorial urn you produce and the fact that you were able to engrave and ship it in so timely a manner. With so many things to do upon the death of a loved one, it was very helpful to have no worries about having an attractive, tasteful memorial urn for the funeral service."
Urn vaults are designed to protect cremation urns from the damage caused by water and erosion. However, urn vaults vary in specifications. Be sure to check with your cemetery rules before choosing an vault.
