The coins all fit in the tubes.

I use bug-loads of these round clear tubes, I like being able to see the edges of the coins.

These tubes are very sturdy and have a nice high quality feel to them. I personally don't use them for nickels, but for storing dice. The are very durable and clean. I've dropped a couple of them while full and not a crack or scratch. Unlike some of the cheaper quality ones I've used in the past, these feel made to last. I'm very pleased with my purchase and will buy them again when I need more.
