I suspect that the warehouse thought they were doing you a favor.

You could also start prepping them yourself before sending them in.

I would say its time to put them in a box yourself. I always think the worse possible way they can ship something and will it survive the warehouse and the shipping company.

Prepare them yourself

I sell grocery items. FBA put some of them in padded envelopes that bottles got crushed and the canned things broke the envelope. So I made labels that say “This item must be shipped in a box. Please box it before shipping”

Amazon gets paid to deal with shipping the FBA stuff. If I have to box every grocery item, I’m quitting.

Amazon isn’t damaging your caps… you are responsible for making sure they can transport safely.

Amazon ships so much stuff, they are not going to take the time to make sure your stuff is safe.

Anything you send into Amazon, assume it won’t have any protection when they ship it and then you will be covered

Knowing how Amazon’s warehouse operates, we send all of our FBA items in fully protected against damage in transit. For instance, we bubblewrap and bubble bag our eyeshadow palettes and stick the Amazon barcode label on the outside of the package before sending in. Amazon is not in the business of ensuring that our fragile items are safely packaged. There are countless reviews of customers receiving an eyeshadow palette that was just thrown in a box from FBA and it arrived broken to bits. I think it is up to the seller to prep a proper package to ensure the safe delivery. Amazon just wants to quickly stick a shipping label on it and out the door it goes.

We sell glass thermometers. We do package them well, but if they are shipped in an envelope they don’t have much hope of arriving intact. Some items, Amazon should KNOW cannot go in an envelope. We’ve escalated this and then we get an item removal because of too many complaints…complaints originating from amazon issues.

Egad…!

I will add that almost everything I send in, can be labeled and shipped on it’s own without Amazon boxing it
