Zip Lock Bags and Plastic storage boxes, brands of Plastic Storage boxes are Sterilite, Rubbermaid, and Tupperware. Many years ago I stored in shoe boxes, somehow and someway some moths got into my storage area destroyed close to $500 or more worth of fly tying material and flies that I had tied. I now use seal tight plastic for storage. Those moths ate everything natural that didn't have dye in it. If the feathers or wool was dyed they didn't touch it. Use plastic with a good seal. If you get some pheasant tail, grouse, or buck tail from a friend put it in the feezer for a couple of weeks before storing it. I learned the hard way, you can't be too careful.
