Looking to warm some hearts via snail mail? This sweet heart design is all about spreading love—whether you're sending a flirty note, gratitude letter, or heartfelt birthday card. Hand illustrated and printed with a combination of flat printing and engraving, these cuties strike a balance of fun and refinement. And this design comes with a special bonus: a portion of all sales from this set will go to Gods Love We Deliver, an organization helping sick and elderly people in NYC get nutritious meals every day.
