-- great neoprene cases for 20 DEM / 10 USD (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=3586)

I found round neoprene cases which normally hold 10 CDs at the swedish origin fashion retail chain H&M (Hennes&Mauritz) for just 20 german bucks. They are great because they hold a Visor and modules and are quite safe.
