It's always a problem to get gifts for those who have everything (you know who you are). Sweetu doesn't quite have that problem as he is such a minimalist, but he is extremely discerning and rather picky. So on his birthday, instead of trying to guess at what Nom de Guerre piece to get him, we made him this stamp instead.
He happens to also be the Sweetest man alive, in name and in nature, so a double S to make a heart symbol was the perfect apotheosis. He can now stamp his sweetness on whatever he wants.
