A tiny press, a big smile—our Self-Inking Kindness Rainbow Postcard Stamp turns everyday notes into little bursts of joy, inviting students and customers to feel seen, appreciated, and inspired.
Crisp linework showcases a three-arch rainbow hovering above a sweet five-petal bloom, paired with the hand-lettered reminder “kindness is golden.” The clean black-and-white artwork pops whether you stamp in classic noir or a bright hue, setting a warm, modern tone on every card and insert.
Sized at 1-5/8" square, this self-inking kindness postcard stamp is engineered for comfort and consistency. Precision-cut metal dies deliver razor-sharp detail; an ergonomic body keeps hands fresh through long batches. Choose from 11 vibrant inks, enjoy up to 10,000 impressions per full pad.
