[Janno]

I found this think that looks like a battery and I want to know what it is. I found it when I broke the black box and it was in a part where I wouldn’t detected it if I didn’t break it.

Hi @Janno

this was definitely caused by human error when assembling the package.
Please note that the battery is not intended to be included and is not needed to use the device, so you can dispose of it.
We apologize for the inconvenience.

Hello Janno

I am certain that is just the magnet on the inside of the package that keeps the trezor box closed (holds the lid).
My trezor has 2 of those on the inside of the package.

Because you broke the black box it must of unglued itself and fell.

Hope this helped
