Common materials include plastic, metal, paper, and polyresin.
Listings commonly recommend ages around 3 years and up (often 3–10), some 6–12, and a few specify teen or adult ranges such as 14+ or 18+.
Paper blowers are generally made of paper (often paired with small plastic components) and are described as reusable or recyclable.
Listed sizes vary; examples include blowouts around 1.5 × 1.5 inches, a blowout listed as approximately 5 × 1.5 × 1.5 inches, a 3" cowbell, and one item with dimensions 2.13 × 7.99 × 2.13 inches.
Mechanisms vary by type: mini trumpets may be tapped to squeak, spinning ratchets are rotated to create a clacking sound, air horns are activated by pressing a top button, and metal cowbells are shaken or rung by hand.
Descriptions list all-metal construction with small top handles; one listing specifically notes a built-in rubber grip handle for more comfortable ringing.
