I put them in 2X2 coin envelopes. They can be moved around as needed. Yes, you have to open the envelope to see them, but to me this is no problem. I am not racing the clock, nor trying to use the most popular "new storage method". I have used this same method of storage for other small disc collectibles since the late 1950's. There is no "bleeding". They will still remain nice this way when my 3 year old grandson gets them down the road, after my time.
