California Dogface Stamps

These stamps are designed specifically for items that cannot be processed through standard automated mail sorting machines, such as bulky envelopes, square envelopes, or those with clasps or strings. By affixing our Non-Machinable Stamps, you’re guaranteeing that your important documents, invitations, or special greetings receive the careful handling they deserve.

Whether you’re sending out unique invitations for a special event or mailing sensitive documents, our Non-Machinable Stamps provide peace of mind, ensuring that your mail arrives safely and in pristine condition, every time.

Every stamp sold here is a genuine United States Postal Service issue, unused, with full original gum and clean perforations. We do not sell reproductions, reprints or novelty facsimiles.

Stampora is an independent retailer and is not affiliated with, authorised by or acting as an agent of the USPS. Our prices sit above face value to cover sourcing, verification, packaging and delivery.

Orders are packed flat and protected so gum and perforations arrive undamaged, then shipped tracked. Delivery estimates are shown at checkout.

If an order arrives damaged or is not the issue you ordered, tell us and we will replace or refund it. See the returns and refunds page for full terms.
