Sometimes guessing which box to use to ship can a crap shoot. But now you can determine which box is best suited for shipping using the USPS Virtual Box Simulator to project box holograms onto the image from your webcam. A transparent virtual box is then simulated to best match with what you plan to ship out...pretty keen! Watch it in action via the video below...

Three easy steps:
Step 1 - Print a special eagle icon to trigger the hologram. Print one now
Step 2 - Turn on your webcam.
Step 3 - Launch the Virtual Box Simulator. Step 4 - Hold the printed eagle icon in front of your cam until a box appears and see how each box measures up to your shipment.

Give it a try here!
