6-8mm diameter Lauscha dark green transparent rods. This looks black in a bundle but you can see the colour when held up to the light. (Photo is taken with light shining through).
You can see in my test beads that it shows up as a very dark bottle green when used as plain spacers - you can tell it isn't black but it's a close thing. Used as stringer over white it gives a good strong green - it should be good for layering.
Average weight per rod: 30g
