Packaging / / Development

There are a lot of questions I need to answer with regards to 
my packaging designs.  For example, how am I going to print 
onto the plastic wallet?  Do I even want to print onto it?  I've
come up with a potential answer for this:
 
Foiling onto the plastic wallet will give the matt effect I am
looking for. 

Some colour schemes i've been looking into:

-i'm thinking dull.  But it also looks reserved, as my target 

audience generally are.  These reserved colours look more 

intelligent than for example, bright yellow, which would

seem rude and boystrous.
