So, What Is The Difference Between TI5 Secret Shop Treasures And The Ones In Game For Purchase?

I searched reddit for this question and couldn't find the answer. I am going to TI5 and I heard legend that there are some rare items you can get by purchasing swag, at least in previous TI's. So of course I bought a crap load of swag with a bunch of digital treasure chests attached.

However now I see that you can just outright buy the locklass, carafe, and the pillar. So is my swag going to be different? I noticed the word "imbued" is before each of them in the secret shop online store.

Is the super secret items you can only get at TI5 physically just a legend I heard? Or founded in some truth? Does the "Imbued" key word mean anything?

EDIT: Updated for those wondering WHAT WE KNOW:

imbued = genuine version

Item 1: You get by getting all the emoticons (via blindboxes, dirty) and you get this: http://steamcommunity.com/market/listings/570/Emoticharm%202015%20Emoticon%20Pack%207%20Bundle

Item 2: You can get the Staglift courier through the plushy drops.

Item 3: ??? :(
