Eh...Jeanie, you 'newbie' ah? Hehehehe...
Hard, lockable (generally) and fairly weather-resistant, crush/shock resistant - Pelican. Not sure if Doskocil has specially for memory cards, but you can check.

Actually got a lot more from all sorts of mfgs, but mostly in the US. Alternatively, search the IT media type stores in the US and UK. They have some beautifully made hard cases for mem cards. I still have my brushed satin aluminium 'vault' with hard purple rubber inserts but too bad for SD cards. These are generally not weather resistant though but some are damned chio looking.
SG Pelikan dealer used to be in Beach Road (opp Golden Mile Complex. Not sure if still there). Can check the Pelican webbie.
