Included with every order

30-Day Money-Back Guarantee

Your thirty days begin the day the costume is delivered — not the day you order — so shipping time never counts against you. If the fit isn't right, or it simply isn't what you pictured, tell us and we'll replace it or refund you in full.

  • No forms

    Send one message. There's nothing to fill in and nothing to print.

  • A person, not a queue

    Replies usually land within a day, from someone who can actually resolve it.

  • Shipping included

    Refunds cover what you paid to have it delivered, not just the item.

Extend your cover to 90 days

Add the 90-Day Warranty in the buy area and your protection runs for three months instead of one, covering seams, stitching, buttons and the spider costume against any defect. If something gives way, we send a replacement and you keep the original.
