How to ship a custom package?
When using this postal option you can use your own boxes, envelopes, or poly-mailers, but you cannot use any of USPS's special Flat Rate packaging. You are able to use the Tyvek Envelope or Priority Shoe Box options when choosing this postage. If you click the link above you will be redirected to USPS's website where you can order the packaging to be delivered to your door.
Priority Mail Tyvek Envelope
Dimensions: 11-5/8" X 15-1/8"(W)
This self-sealing envelope is a durable, water resistant shipping option that is good for documents or small items.
Poly-mailer vs. Bubble-mailer
You can purchase these through Amazon or where ever you purchase your other postal needs.
Bubble-mailers also come in a variety of sizes. These envelopes are a good option if your products need a little extra padding when shipping.
Priority Mail Shoe Box
Inside Dimensions: 7-1/2"(L) X 5-1/8"(W) X 14-3/8"(H)
Outside Dimensions: 7-3/8"(L) X 5-1/4"(W) X 14-7/8"(H)
This packaging was designed for clothing retailers and direct-to-customer businesses. Roughly the same size of a box of shoes, this item is good for clothing or multiple items orders.
You can also purchase Express Shipping through our system when using Priority - Custom Package. You must use your own packaging when choosing this option. After entering the dimensions and weight, you'll check "Express Shipping" to get a quote for express shipping the package.
