Thanks so Far, I am recording every brand and sizes you tell me about, looks like I need to buy some tips to check the size of the packages.
Some say my hands, my fingers, still not the question nor the answer.
A rolling tray is something I needed and I end up designing my own. Made another simple one to offer, and was well accepted.
Now I want do design 3 main lines and 2 models per line of rolling trays.
It is important that the tray hold all you need or you have in one place in a order fashion, for me is the easy to hide ability that made me made mine but I can do more 
So I am trying to get the most usable slots in the small ammount of tray.
Here is mine:

And the smaller one:
Oh, it is good because of some bits that come off when rolling and upside down you can cut your hash like a cutting board! As a last resort it can be used as timber.
