Lens Filter Case

[GreatMoloko]

So I got the "poor man's macro" lens set (1x, 2x, 4x, 10x lens filters) and a reverse coupler thinger-ma-jigger-bobber as a gift so these 5 + my 2 UV protectors + 1 Circular Polarizer = a bunch of lens filter-deals floating around my camera bag.

Anyone have any suggestions for proper, safe/secure, storage of lens filters?

I looked on amazon and saw some LowerPro and other brand filter cases that hold # of filters, but does anyone have experience with these? (I trust you all more than the comments on Amazon)

Or any other, preferably cheaper/free, ideas?

Thanks in advance!
