Your pet’s ashes can either stay in the bag or be removed from the bag. While some people place the bag of ashes directly into the urn, others prefer to take the ashes out of the bag and place just the ashes into the urn. Many urns have some way in which they close. Some have screws, some have tops, and some have plugs. A person may choose to use glue on the closing mechanism to ensure the urn does not open. One may choose not to permanently seal the urn, such as in the event of spreading the remains.
