Even in this age of emails and online transactions, snail mail has not disappeared. I started offering these mail holders after numerous requests for a key holder that would hold envelopes. Each piece varies because I use authentic vintage license plates so if you see that an item is temporarily out of stock, please contact me. The next one will have the same image but a different vintage license plate from the same state. I also take requests for custom orders using either your license plates and images or materials from my own collection. Please contact me through my special order form.
