6G-Blocking Lip Balm

The mouth is an open aperture. Whatever shielding you wear around the skull is undone by an unshielded lip line every time you speak. This balm closes the gap.

The bismuth content is well below any toxicological threshold and is present in metallic particle form, oriented during the setting process to lie flat against the lip surface. The balm itself looks and tastes like a normal tinted balm. No one will ask questions.

Re-apply every 2 hours, or after any sustained conversation with a stranger.
