This custom soft pouch designed by Michael has a secret: It has a built in lens filter cloth sewn to the inside! This is not only great for cleaning lenses, but also handy to separate different filters from one another. Can hold up to 3 MAVEN Magnetic rings. Wait, did we say magnetic? Is there a new line of filters coming? (Hmmm....looks like it!) This little pouch is designed to hold your 100 x 100 filters, threaded filters and so much more. We send them out free with each 100x100 purchase, but if you want more, you have come to the right place!
