USPS Flat Rate Boxes Are Now Shipped Anywhere In The U.S. For FREE!!!

We at Second Skin know the shipping can get costly on heavy products, so we offer these boxes which include as much product as we can fit inside of the USPS Flat Rate Box service. They usually arrive in 2-3 business days to most locations in the United States. Perfect packages for smaller projects or when you didn't get enough the first time and need some more fast and cheaper. We can also ship these boxes to most countries around the globe for a good price, just email us at to request shipping quotes (we will need your full shipping address and product list).

Complete Packages Are The Easiest Way To Go!!!

At Second Skin for the past 18 years we get repeated calls for certain types of projects and even sometimes certain project vehicle sizes. While we do not offer custom cut layouts (as that makes the cost increase) we do offer package sizes that fit most vehicles out there. From Small Build Packs to XXL Build Packs, from Audio Door Kits to Large Trunk Kits, and from Jeep Packages to Corvette Packages, we have a bundle package that may be right for your build and will be offered at a great bundle deal discount.
