2 pack of .5ML conical plastic tube with screw top lid and o-ring.
Great for making those creative cache containers. This makes for a watertight geocache that you can almost hide anywhere keeping geocachers wondering where it is.
Each container has a Rite in the Rain log sheet included. (3/4" x 11" is recommended).
Picture shows a comparison to a 1.5ml tube. (1.5ml tube not included)
