I was very pleased with the quality of the Heart to Heart Mug Set. The personalization was well done. The ink was dark enough to match the hearts on the mugs. It didn't look like the names were just stamped on, but rather part of the entire color makeup of the mug. However, I didn't notice the "I" that was written above the heart, until I saw them at home. The cup and handles seem strong, rather than light and thin. The indented cup, however, is quite small and would unlikely be used for a cup of coffee. The set makes a very nice knickknack. Both of my adult children and their mates loved getting them for Valentine's Day, though I think they would also be a unique gift for a bridal shower,wedding or anniversary.
