This are small glass vials with cork stoppers. They are ideal for the storage of meteorite micromounts, mineral crumbs, or any specimen sample you can fit inside.
They have a 5-ml storage capacity. They measure approx. 40mm in length and 18mm in width. I am offering these in lots of three (3) vials each.
Refer to the photo. The black centimeter cube is shown for scale and is not included. You are purchasing three (3) vials like the ones shown.
