Proof you mailed it.

Custos Proof documents every card you ship, giving you the evidence you need to win a claim if it’s lost, stolen, damaged, or disputed.

  • Lost or damaged in the mail? Hand your carrier or insurer the packet.
  • Buyer says it never arrived? They confirmed the deal, and you have the photos.
  • Deal feels too good to be true? Your buyer confirms before you ship.

Questions

The short answers.

Is this insurance?

No. It's your proof. If you insured the package, it covers most of what insurers ask for, and page 1 says what to add and when to file. If you didn't, it's your evidence if a buyer disputes the sale.

Does Custos touch my card?

No. You pack and ship it the way you always do. We record what you photographed and what your buyer confirmed.

Can I use photos I already took?

No. Photos come straight from your phone's camera while you pack. A photo taken more than 30 minutes earlier is refused.

What if my buyer never answers?

Your photos and their times stay on the record, and the packet shows your buyer was emailed and when.

Can I get my $1.99 back?

Once you've added a photo, no. If something on our side stops you finishing, email anthony@custoscards.com and we'll refund it.
