I bought two sets of these in the bride and grooms favorite colors for wedding shower gifts for a couple that like to travel. It was fun to present it to the bride with her new monogram and she really liked it. The quality was really nice and I received them quickly. Hopefully the monogram holds up and doesn't rub off. Time will tell.
