sticker

Hi Browncafe I just got hired yesterday, and tonight will be my 2nd day of training. My question is: Where do I get sticker and do I need it for the portable music player also? On the first training, They told me that I have to have a sticker for a phone if I bringing it, but my English is not...

So my friends and I want to get some walkie talkies and UPS polo shirts to act like we're supervisors as kind of like a jokes. And so I'm wondering if we're able to get the stickers for the walkies? Kind of like we do our phones. Each walkie has a serial number.
