We thought of that too! And no, the buyer will NOT know you returned the gift they picked out especially for you :)
Please visit the new Sanrio.com Returns Center and select "Returning a Gift?" and follow the instructions!
Within 7 days of us receiving the product(s), you will receive an e-Gift Card via email for use at Sanrio.com. e-Gift Cards do not expire.
Please note that customers from Canada and Mexico must return items at their own cost.
