I found a single photo box about this size at Hobby Lobby. I like it because it keeps them pretty safe and covered from dust. Be careful fidgeting with getting the scales just right in the silicone, I spent a lot of time and got silicone everywhere and they moved all on their own over night.... Seems like all my work was a waste of time, but the mold still works pretty darn good.
I also did it backwards than the instructions state. You're supposed to pour it over the item, I just poured it and place the scales in there. BUT, I do have some air bubbles that need to be fixed on the new scales. Quick and easy knife work though.
