The instructions on the back of the package read as follows.
Directions for use:
• Open a bottle only to add to its contents; reseal it quickly.
• Keep contents in bottles and sealed at all times when not in use.
• Once inside the bottle, do not let emotions back out.
These containers are designed for adult use. The lids are not childproof. Store out of reach of children and/or emotionally labile adults. In case of accidental ingestion or overdose, give child a time out. For adults, immediately induce crying. If that fails, consult a therapist immediately.
In a later incarnation, the bottled emotions became an installation piece covering the walls of my bathroom, portions of which may be seen below.
