Teaching your children about snail mail could take them back to a simpler time and away from their electronic devices. With this Unicorn princess return address stamp, you can show them how to write a letter and stamp their envelope with their name and address on it just before they put a postage stamp on it. Makes a great birthday gift! Most orders ship within 24 hours and have a money back guarantee. Why buy extra ink? Your kids stamp will last for numerous impressions, much longer than the ink that comes with it. Purchasing extra ink with your stamp will ensure that you will get full value from your stamp for years to come. Order ink with your stamp and don't run out of ink on the day you need it the most!
