I am looking for advice to add a tamper evident seal to a branded product sold via Amazon FBA. The brand does not have these as supplied to me. I am looking to enhance the customer experience and quality reassurance. It is not my brand but am an authorised reseller.

The product is packaged in a colour retail box, containing a bottle inside of liquid. The bottle itself has a double seal (foil seal and cap.)

If permitted I would add these to the product as part of our QA process prior to shipping the goods to FBA.

Are there any guidelines surrounding this please?

Thank you.
