What's a good picture to use for Lost & Found?

So for some context, as I recognise that this might seem like a strange question at first… Recieved as a Christmas Gift, a system of tagging that enable to create an inventory for lost items-- people are losing items left right and centre (myself included I might add!), and I’m hoping not to lose my phone in the forseeable future! Problem is, I’m having issues describing the phone in question-- I.e to a person who is not familiar, or who has otherwise never heard of TERACUBE as a brand in general… Would the Developers have some good photos that I might be able to use for this purpose? In an ideal world, I’d be wanting to use some of the same photos/images that were used in the marketing for the TERACUBE 2E, however, I’m aware that there may be issues with Intellectual Property Rights (IP), and don’t want to get myself into any legal issues you understand!

For further context than I have already provided, the system of tagging works that when the item in question is lost, the person scans a QR code and is then able to receive info (you can customise this section!) to add for the purposes of retrieving the item in question to its rightful owner… The description of the item, in this way, is supposed to be a verification process to the purpose reading the message that said item is indeed your own!
