I like the Iris or Art Bin scrapbooking storage containers. See through, sturdy, stackable, very portable ( the Art Bin brand have nice handles), and they snap shut. I like the ones that are marketed for 12x12 scrapbook paper storage, because they're really 14" square so the hold a lot of whatever I have cut (strips, charms, candies) and I can keep an entire project together in one. I don't have many yet ( I've used other storage methods from shoeboxes to baskets, but when one of those spills, Look out! I nearly lose my Christianity.
No, I don't like pinked edges.
So far I've not bought pre-cuts, but if I do, I will have to open them immediately and pet them and drool. Then I would store them together with their label for reference in one of the Art Bins I mentioned .
