There is a choice of 'open end up', with the glass tubes secured in place with the open ends upwards, or 'open end down', with the glass tubes secured in place with the open ends down, as they would be stored in the laboratory.
The wooden rack is 1 1/2 inches across, and the silver plated chain is 23 inches long, with a lobster clasp. If you would like the chain to be longer or shorter please ask - no additional charge.
This necklace comes in a gift bag.
