No, you don't need to worry.
As the name says, the completion/shipping estimate for custom made items is just an estimate. In most cases we manage to finish your order and dispatch it a few days earlier than expected.
But it can happen that there's a delay - due to large volume of custom orders or because some small details needs to be remade - and your order might ship a few days later than expected.
As soon as your order is ready, we ship it to you and send the tracking information by email so you can follow it until final delivery.
Please feel free to contact our support team if you have a deadline such as graduation os special competition and we'll do our best to fast track your order.
