As advised by most hardware wallet owners, you should buy only from trusted sellers. I bought my Trezor Model T cryptocurrency hardware wallet directly from the trezor.io website.
Upon receiving the product, I visited this https://wiki.trezor.io/User_manual:Unboxing_the_Trezor_device to check if the items listed in the site are present in the package that I received.
A package with Trezor T contains the following:
- Trezor Model T device with a holographic seal over the connector
- USB cable (type C)
- Getting started card (package)
- Magnetic dock
- Recovery seed card (12 words) 2x
- Sticker 4x
