This dental floss was part of an oral hygiene kit deisgned for use by the astronauts during the Apollo missions of the 1960s and early 1970s.
The complete kit consisted of two toothbrushes, one tube of toothpaste and one roll dental floss. Oral hygiene was an important part of the astronaut's health and well being, and the kit was designed to have toothbrushes, toothpaste and dental floss. Due to the difficulties associated with a weightless environment, toothpaste was created that could be swallowed.
This particular kit has one pink and one blue toothbrush, has the toothpaste and dental floss, but is without the bag/container, and was never flown or used.
Transferred from NASA to the National Air and Space Museum in 1975
