These are the 75ml polystyrene unbreakable test tubes we once used to package our mica. They are quite wonderful for storage, for sea-faring "notes in a bottle", to add to mail art collages in soda pop bottles, to start seedlings, as a vase for a single bud, to tie together as a container for found objects, the list goes on…
Comes with tight fitting, but removable, plastic cork. Tube is just about 1/2 inch in diameter and 3 inches long. The cap adds another 1/2 inch to the length of the tube.
We're showing several test tubes for illustration.
