Product packaging

I've been "auditioning" a bunch of existing products to get
a better feel for packaging ("encapsulation?") options.
A necessary condition is that devices be easily cleaned,
without the benefit of sight (so people aren't "grossed out"
by the accumulated dirt and grime on a device used by an
unsighted individual:  "Don't you ever CLEAN that?")
But, glossy smooth finishes are pretty boring (not everyone
is blind; a product should appeal to sighted users as well!).
Texturing the mold is an option -- as long as the resulting
texture isn't too aggressive AND the material flows well
enough to take on that level of fine detail.
There seem to be some coatings that are widely used.  But,
they don't seem to hold up over the long term -- many get
"tacky" as if a plasticizer shit the bed (?)
And, a sheath/condom could also be used at some increase in
manufacturing and maintenance costs (ensuring the sheath can
be removed, cleaned and replaced -- but not LOST -- without
also providing opportunities for "crud" to collect in any
gaps or "seams")
I suspect most folks don't design handheld devices?  Or,
wearables?  But, for any who *do*, can you shed some light
on how your packaging decisions are made -- along with
the expected lifetimes of the affected products?  (i.e., if
something will be discarded before it "wears", then the
decision is largely moot)
