Birthday Rubber Stamps for Card Making

Everyone you know has a birthday — be ready for all of them. Unity’s birthday rubber stamps are hand-drawn by our artists and manufactured in-house in New London, Minnesota, from deeply etched red rubber that delivers crisp, detailed impressions for years of celebrations.

Browse more than 250 birthday stamp designs: cakes and candles, balloons and confetti, party animals (literally), and sentiments from sweet to snarky — because some friends deserve “happy birthday, beautiful” and others need a card as funny as they are. Milestone birthdays, kids’ birthdays, belated birthdays: covered.

Each set is cling-mounted, MISTI-friendly, and ready for any acrylic block. Pair with coordinating dies for cake-topper-worthy layers — handmade in the USA and shipped fast from our Minnesota shop.

Need words to match the stamp? Our guide to 90 snarky birthday wishes is full of card-worthy sass.
