Hi Jerry. I store all of my Wacky's in top loader clear plastic boxes, using either 100 or 150 capacity boxes depending on how many extras I have for a given set. I just feel they are more protected inside the hard plastic boxes, and I can easily access them if need be. Gauranteed I can't see the entire collection at once, but for me it's more about keeping them safe.
If you're interested in buying them you can usually find them at any local gaming store for around $1 for the 100 capacity box and $1.50 for the 150 capacity box, so it won't cost much to protect your entire collection.
