Our shipping charge covers the cost of shipping the fingerprint kit from us to you and your finished product from us to you. The method and cost of returning the kit to us is up to you–a Priority Flat Rate Envelope or Small Flat Rate Box is easiest and will cost you about $6 domestic. The boxes and envelopes are free at the Post Office. First Class is also an option and will cost you a bit less, but you will need to package the materials and tape it up yourself. Shipping jewelry to international locations is expensive. We use FedEx to ensure that your jewelry gets through customs and to you in time for your wedding. If you are not from the US you may have customs fees that are not included in our shipping charge. Please do not ask us to mark a package differently to avoid fees. There are hefty fines associated with that and we could lose our business.
