I don't quite know who this product is targeting.  The Memory Card Travel Case from Digital Foci is a hardened carrier for memory cards.  The inside provides custom moldings to hold just about any media card format known to man.  The case can be yours for $19.95.

From the image and the description, it seems that it's only one case.  That one case has moldings for ALL memory cards.  Who carries that many different memory cards with them, and needs a protective case for all of them?  I roll with SD and CF memory cards.  Yes, I've got a handful of both.  I could find usefullness in Digital Foci's card case if it had say, interchangeable moldings, so you could special-order specific card moldings.  Or maybe if they sold a specific case for each card format.  But as is, I don't think it's a very useful product.  I'll stick to the padded camera case they stay in anyway...
