Difference In Plastic Tube Brands

Honestly, I don't know which brand is the best. I've used Harris coin tubes for years and they seem to hold up well (fairly inexpensive too).

I heard the square tubes are not that good. something about the plastic being too soft.
PVC ? I use Whitman clear round , I only pay .25 each. never had a problem.

So does anyone have info on "Koin Tubes"? I found a deal for less than 30c a piece shipped which works for me. I cant find a webpage or anything that shows what they are made of though. I don't want them to damage my coins!

oh, and of course, pennies wud slide around in nickel tubes. this is why tubes are designed for the type of coin you want. So for pennies, you want penny tubes. For nickels, you want nickel tubes, etc. I recommend NOT using tubes for a *different* coin than what you put in them. I think that defeats several purposes. we know that pennies come in 50 pennies per roll, and nickels rolls are $2 rolls with 40 nickels. but I have no idea how many pennies wud fit in a tube for nickels. the reason I put my coins in tubes is so that I can easily count them by the roll. I think non-conformance to this wud be counter-productive. but 'to each his own'. you can do what you want. :)
