Have USPS insurance experience?

[Luv2Roam]

I bought a nice Disney related item on Ebay. (Not pins)
Luckily the sender insured, as when I received the items (3 piece canister set) two of the three are broken way beyond any repair.
It was sent priority and the seller packed it well, but obviously not quite good enough.
I have never had experience with filing a USPS insurance claim.
The seller says I just need to take in the mailing label and a number she gave me for the insurance.
Is this correct?
It's not a lot of money. I am just glad it was insured. Do I get a full refund? Partial refund? Refund including shipping? How does this work?
I figure maybe just taking the box/contents in and my Paypal receipt.

Here's what the USPS web site says..

Evidence of Insurance
Submit evidence that Insured Mail, Collect on Delivery (COD), Registered Mail™, or Express Mail® was purchased for the mailed package. The original mailing receipt that you were given at the time of mailing is the preferred evidence. Check the General Filing Instructions for a detailed list of acceptable evidence.

Evidence of Value
Submit evidence - such as a sales receipt or invoice - showing the value of the article when it was mailed. Check the General Filing Instructions for a detailed list of acceptable evidence.

Proof of Damage or Loss
If the article was damaged - or if some or all of the contents were missing - take the article, box, wrapper, and all packing materials to your local Post Office immediately. If the article was lost, submit any of the following as proof of loss:

A letter or statement from the addressee - dated at least 30 days (15 days for registered mail) after the date the article was mailed - stating that the addressee did not receive the article. The statement, or a copy of it, must be attached to the claim.
A claim form completed by the addressee - indicating that the article was not received - that has been signed and returned to the sender.
A statement from the addressee's Post Office indicating that a delivery record is not on file.
