Magellan, if you ever need to rid yourself of the lesser cell holders, my name is WarRaven and my address...☺
what do you think of the polypropylene one? Would it be as tough is the derlin? Thought about picking one up...would add a splash of color with a red cell in it.
It's hard to tell if it's just as tough but I can tell you it doesn't seem fragile for sure. I'd say it's pretty close to the Delrin.
