These little things make nice little containers for what ever you want. They use the same screw on tops as 2 liter bottles. They are about 5 inches long.
Nice thing about them using 2 liter tops leads to a nice advantage if you need a small container for somehting double the length. A Vortex tube with the hole enlarged (drilled out)- the kind used in elementary science- can join two together to give you a longer container.
