"We ordered this stamp to use for return addresses on our wedding invitations and response cards, and it turned out beautiful. However, we were not actually able to use the stamp for this purpose because the ink did not set on the envelopes. It smeared due to the ink being water based. Be wary of this if you are using the pearl white shimmer envelopes from WPD. I really wish we would have been able to use this for our invitations because it is a beautiful stamp."
