What can I ship through Custom Package - Priority?

Simplified Shipping: Custom Priority Packages with USPS

Shipping a custom priority package

When using this postal option you can use your own boxes, envelopes, or poly-mailers. If you need packaging, USPS offers a convenient solution. They will ship pre-filled custom packaging to your door for FREE. To order the packaging, click on the links provided below. You will be redirected to USPS's website where you can place your order and have the packaging delivered to your door.

They have two options for priority mail: Priority Mail Tyvek Envelope and Priority Mail Shoe Box. 

You cannot use any of USPS's Flat Rate packaging when shipping a "custom package." We have separate prices for flat rate package.

Packaging Details

Poly-mailer vs. Bubble-mailer Dimensions: Varies

You can purchase these through Amazon or where ever you purchase your other postal needs.

Poly-mailers come in a variety of sizes and you can often purchase them in bulk or in a variety of colors. Poly-mailers are thin plastic envelopes that are good for shipping non-fragile items.

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.
