After reading BatNinja's Ammo Pouch Tutorial I figured that I could make my own hollow box. I made one out of sintra then just made a mold of it. Now they are all the same size. I would show the one out of sintra but, I had to take it apart to get it out of the mold. They do not have to be black. If I did not add any tint they would be clear. The only item I don't like is that I had to make a hole in the bottom so that I can get the out of the mold. What do you think?
