Most listings specify that the mustaches are made from polyester.
Some are self-adhesive stick-on mustaches, while others are shaped pieces you bend and secure to the face.
Listed dimensions vary widely across listings. Examples given include 3.0" x 1.0", 1.0" x 12.0", 0.1" x 3.8", and one listing notes a 5.5" length.
Recommended ages vary by listing; examples include “3 years and up” and “14 years and up.”
Pack counts vary by listing; examples shown include 1-piece, 2-piece, and 3-piece sets.
Some sets include a beard along with the mustache, and some stick-on mustaches can be trimmed to create a beard-like look.
Some mustaches are advertised as shapeable into multiple styles (for example, ‘six ways’) and easy to secure, while others are realistic stick-ons that can be trimmed for different looks.
